Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22312, here are decompositions:

  • 5 + 22307 = 22312
  • 29 + 22283 = 22312
  • 41 + 22271 = 22312
  • 53 + 22259 = 22312
  • 83 + 22229 = 22312
  • 179 + 22133 = 22312
  • 233 + 22079 = 22312
  • 239 + 22073 = 22312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22312 first appears in π at position 135,865 of the decimal expansion (the 135,865ordinal-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.
