Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17656, here are decompositions:

  • 29 + 17627 = 17656
  • 47 + 17609 = 17656
  • 59 + 17597 = 17656
  • 83 + 17573 = 17656
  • 137 + 17519 = 17656
  • 167 + 17489 = 17656
  • 173 + 17483 = 17656
  • 179 + 17477 = 17656

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17656 first appears in π at position 4,418 of the decimal expansion (the 4,418ordinal-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.
