Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26720, here are decompositions:

  • 3 + 26717 = 26720
  • 7 + 26713 = 26720
  • 19 + 26701 = 26720
  • 37 + 26683 = 26720
  • 73 + 26647 = 26720
  • 79 + 26641 = 26720
  • 163 + 26557 = 26720
  • 181 + 26539 = 26720

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26720 first appears in π at position 85,550 of the decimal expansion (the 85,550ordinal-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.
