Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15936, here are decompositions:

  • 13 + 15923 = 15936
  • 17 + 15919 = 15936
  • 23 + 15913 = 15936
  • 29 + 15907 = 15936
  • 47 + 15889 = 15936
  • 59 + 15877 = 15936
  • 113 + 15823 = 15936
  • 127 + 15809 = 15936

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15936 first appears in π at position 165,218 of the decimal expansion (the 165,218ordinal-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.
