Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23156, here are decompositions:

  • 13 + 23143 = 23156
  • 97 + 23059 = 23156
  • 103 + 23053 = 23156
  • 127 + 23029 = 23156
  • 139 + 23017 = 23156
  • 163 + 22993 = 23156
  • 193 + 22963 = 23156
  • 349 + 22807 = 23156

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23156 first appears in π at position 182,014 of the decimal expansion (the 182,014ordinal-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.
