Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26886, here are decompositions:

  • 5 + 26881 = 26886
  • 7 + 26879 = 26886
  • 23 + 26863 = 26886
  • 37 + 26849 = 26886
  • 47 + 26839 = 26886
  • 53 + 26833 = 26886
  • 73 + 26813 = 26886
  • 103 + 26783 = 26886

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26886 first appears in π at position 236,253 of the decimal expansion (the 236,253ordinal-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.
