Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11904, here are decompositions:

  • 7 + 11897 = 11904
  • 17 + 11887 = 11904
  • 37 + 11867 = 11904
  • 41 + 11863 = 11904
  • 71 + 11833 = 11904
  • 73 + 11831 = 11904
  • 83 + 11821 = 11904
  • 97 + 11807 = 11904

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11904 first appears in π at position 35,981 of the decimal expansion (the 35,981ordinal-suffix:st 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.
