Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11312, here are decompositions:

  • 13 + 11299 = 11312
  • 61 + 11251 = 11312
  • 73 + 11239 = 11312
  • 139 + 11173 = 11312
  • 151 + 11161 = 11312
  • 163 + 11149 = 11312
  • 181 + 11131 = 11312
  • 193 + 11119 = 11312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11312 first appears in π at position 122,593 of the decimal expansion (the 122,593ordinal-suffix:rd 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.
