Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31926, here are decompositions:

  • 19 + 31907 = 31926
  • 43 + 31883 = 31926
  • 53 + 31873 = 31926
  • 67 + 31859 = 31926
  • 79 + 31847 = 31926
  • 109 + 31817 = 31926
  • 127 + 31799 = 31926
  • 157 + 31769 = 31926

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31926 first appears in π at position 91,384 of the decimal expansion (the 91,384ordinal-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.
