Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31758, here are decompositions:

  • 7 + 31751 = 31758
  • 17 + 31741 = 31758
  • 29 + 31729 = 31758
  • 31 + 31727 = 31758
  • 37 + 31721 = 31758
  • 59 + 31699 = 31758
  • 71 + 31687 = 31758
  • 101 + 31657 = 31758

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31758 first appears in π at position 105,262 of the decimal expansion (the 105,262ordinal-suffix:nd 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.
