Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12992, here are decompositions:

  • 13 + 12979 = 12992
  • 19 + 12973 = 12992
  • 73 + 12919 = 12992
  • 103 + 12889 = 12992
  • 139 + 12853 = 12992
  • 151 + 12841 = 12992
  • 163 + 12829 = 12992
  • 193 + 12799 = 12992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12992 first appears in π at position 47,038 of the decimal expansion (the 47,038ordinal-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.
