Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31732, here are decompositions:

  • 3 + 31729 = 31732
  • 5 + 31727 = 31732
  • 11 + 31721 = 31732
  • 83 + 31649 = 31732
  • 89 + 31643 = 31732
  • 131 + 31601 = 31732
  • 149 + 31583 = 31732
  • 191 + 31541 = 31732

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31732 first appears in π at position 785 of the decimal expansion (the 785ordinal-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.
