Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31002, here are decompositions:

  • 19 + 30983 = 31002
  • 31 + 30971 = 31002
  • 53 + 30949 = 31002
  • 61 + 30941 = 31002
  • 71 + 30931 = 31002
  • 109 + 30893 = 31002
  • 131 + 30871 = 31002
  • 149 + 30853 = 31002

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31002 first appears in π at position 16,365 of the decimal expansion (the 16,365ordinal-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.
