Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11826, here are decompositions:

  • 5 + 11821 = 11826
  • 13 + 11813 = 11826
  • 19 + 11807 = 11826
  • 37 + 11789 = 11826
  • 43 + 11783 = 11826
  • 47 + 11779 = 11826
  • 83 + 11743 = 11826
  • 107 + 11719 = 11826

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 11826 first appears in π at position 68,137 of the decimal expansion (the 68,137ordinal-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.
