Indeed, the next prime is 100,363, the second prime pair over 100,000.

And it is really not far until the next pair

Until then:
100.379

Checking the next non-obvious numbers

100,381 (37)
100,387 (7)

The next prime is 100,391

About time to revive this one again.

100.411

pdurrant · 10-17-2011, 11:09 AM

100,417

Interestingly, the sum of this one's digits (13) is also prime, as was the sum of the digits of the previous prime (7).

100,447

Unfortunately, this sums to 16, so breaks the secondary prime sequence.
