Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26656, here are decompositions:

  • 23 + 26633 = 26656
  • 29 + 26627 = 26656
  • 59 + 26597 = 26656
  • 83 + 26573 = 26656
  • 167 + 26489 = 26656
  • 197 + 26459 = 26656
  • 233 + 26423 = 26656
  • 239 + 26417 = 26656

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26656 first appears in π at position 250,920 of the decimal expansion (the 250,920ordinal-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.
