Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31282, here are decompositions:

  • 5 + 31277 = 31282
  • 11 + 31271 = 31282
  • 23 + 31259 = 31282
  • 29 + 31253 = 31282
  • 59 + 31223 = 31282
  • 89 + 31193 = 31282
  • 101 + 31181 = 31282
  • 131 + 31151 = 31282

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31282 first appears in π at position 39,457 of the decimal expansion (the 39,457ordinal-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.
