Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31756, here are decompositions:

  • 5 + 31751 = 31756
  • 29 + 31727 = 31756
  • 89 + 31667 = 31756
  • 107 + 31649 = 31756
  • 113 + 31643 = 31756
  • 149 + 31607 = 31756
  • 173 + 31583 = 31756
  • 239 + 31517 = 31756

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31756 first appears in π at position 470,547 of the decimal expansion (the 470,547ordinal-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.
