Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26906, here are decompositions:

  • 3 + 26903 = 26906
  • 13 + 26893 = 26906
  • 43 + 26863 = 26906
  • 67 + 26839 = 26906
  • 73 + 26833 = 26906
  • 193 + 26713 = 26906
  • 223 + 26683 = 26906
  • 349 + 26557 = 26906

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26906 first appears in π at position 178,108 of the decimal expansion (the 178,108ordinal-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.
