Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15922, here are decompositions:

  • 3 + 15919 = 15922
  • 41 + 15881 = 15922
  • 113 + 15809 = 15922
  • 131 + 15791 = 15922
  • 149 + 15773 = 15922
  • 173 + 15749 = 15922
  • 191 + 15731 = 15922
  • 239 + 15683 = 15922

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15922 first appears in π at position 145,500 of the decimal expansion (the 145,500ordinal-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.
