Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26986, here are decompositions:

  • 5 + 26981 = 26986
  • 59 + 26927 = 26986
  • 83 + 26903 = 26986
  • 107 + 26879 = 26986
  • 137 + 26849 = 26986
  • 173 + 26813 = 26986
  • 227 + 26759 = 26986
  • 257 + 26729 = 26986

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26986 first appears in π at position 12,994 of the decimal expansion (the 12,994ordinal-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.
