Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11916, here are decompositions:

  • 7 + 11909 = 11916
  • 13 + 11903 = 11916
  • 19 + 11897 = 11916
  • 29 + 11887 = 11916
  • 53 + 11863 = 11916
  • 83 + 11833 = 11916
  • 89 + 11827 = 11916
  • 103 + 11813 = 11916

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11916 first appears in π at position 95,428 of the decimal expansion (the 95,428ordinal-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.
