Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588422, here are decompositions:

  • 23 + 31588399 = 31588422
  • 53 + 31588369 = 31588422
  • 71 + 31588351 = 31588422
  • 101 + 31588321 = 31588422
  • 109 + 31588313 = 31588422
  • 223 + 31588199 = 31588422
  • 251 + 31588171 = 31588422
  • 293 + 31588129 = 31588422

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31588422 first appears in π at position 460,586 of the decimal expansion (the 460,586ordinal-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.
