Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39658, here are decompositions:
- 89 + 39569 = 39658
- 107 + 39551 = 39658
- 137 + 39521 = 39658
- 149 + 39509 = 39658
- 197 + 39461 = 39658
- 239 + 39419 = 39658
- 317 + 39341 = 39658
- 419 + 39239 = 39658
Showing the first eight; more decompositions exist.

The digit sequence 39658 first appears in π at position 5,008 of the decimal expansion (the 5,008ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
