Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26940, here are decompositions:

  • 13 + 26927 = 26940
  • 19 + 26921 = 26940
  • 37 + 26903 = 26940
  • 47 + 26893 = 26940
  • 59 + 26881 = 26940
  • 61 + 26879 = 26940
  • 79 + 26861 = 26940
  • 101 + 26839 = 26940

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26940 first appears in π at position 125,963 of the decimal expansion (the 125,963ordinal-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.
