Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31330, here are decompositions:

  • 3 + 31327 = 31330
  • 11 + 31319 = 31330
  • 23 + 31307 = 31330
  • 53 + 31277 = 31330
  • 59 + 31271 = 31330
  • 71 + 31259 = 31330
  • 83 + 31247 = 31330
  • 107 + 31223 = 31330

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31330 first appears in π at position 163,806 of the decimal expansion (the 163,806ordinal-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.
