Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26808, here are decompositions:

  • 7 + 26801 = 26808
  • 31 + 26777 = 26808
  • 71 + 26737 = 26808
  • 79 + 26729 = 26808
  • 97 + 26711 = 26808
  • 107 + 26701 = 26808
  • 109 + 26699 = 26808
  • 127 + 26681 = 26808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26808 first appears in π at position 57,455 of the decimal expansion (the 57,455ordinal-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.
