Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31924, here are decompositions:

  • 17 + 31907 = 31924
  • 41 + 31883 = 31924
  • 107 + 31817 = 31924
  • 131 + 31793 = 31924
  • 173 + 31751 = 31924
  • 197 + 31727 = 31924
  • 257 + 31667 = 31924
  • 281 + 31643 = 31924

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31924 first appears in π at position 571,714 of the decimal expansion (the 571,714ordinal-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.
