Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31922, here are decompositions:

  • 31 + 31891 = 31922
  • 73 + 31849 = 31922
  • 151 + 31771 = 31922
  • 181 + 31741 = 31922
  • 193 + 31729 = 31922
  • 199 + 31723 = 31922
  • 223 + 31699 = 31922
  • 349 + 31573 = 31922

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31922 first appears in π at position 153,238 of the decimal expansion (the 153,238ordinal-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.
