Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31264, here are decompositions:

  • 5 + 31259 = 31264
  • 11 + 31253 = 31264
  • 17 + 31247 = 31264
  • 41 + 31223 = 31264
  • 71 + 31193 = 31264
  • 83 + 31181 = 31264
  • 113 + 31151 = 31264
  • 173 + 31091 = 31264

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31264 first appears in π at position 159,104 of the decimal expansion (the 159,104ordinal-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.
