Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40856, here are decompositions:

  • 3 + 40853 = 40856
  • 7 + 40849 = 40856
  • 37 + 40819 = 40856
  • 43 + 40813 = 40856
  • 97 + 40759 = 40856
  • 157 + 40699 = 40856
  • 163 + 40693 = 40856
  • 229 + 40627 = 40856

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40856 first appears in π at position 138,313 of the decimal expansion (the 138,313ordinal-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.
