Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23186, here are decompositions:

  • 13 + 23173 = 23186
  • 19 + 23167 = 23186
  • 43 + 23143 = 23186
  • 127 + 23059 = 23186
  • 157 + 23029 = 23186
  • 193 + 22993 = 23186
  • 223 + 22963 = 23186
  • 379 + 22807 = 23186

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23186 first appears in π at position 102,697 of the decimal expansion (the 102,697ordinal-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.
