Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15658, here are decompositions:
- 11 + 15647 = 15658
- 17 + 15641 = 15658
- 29 + 15629 = 15658
- 89 + 15569 = 15658
- 107 + 15551 = 15658
- 131 + 15527 = 15658
- 191 + 15467 = 15658
- 197 + 15461 = 15658
Showing the first eight; more decompositions exist.

The digit sequence 15658 first appears in π at position 167,743 of the decimal expansion (the 167,743ordinal-suffix:rd 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.
