Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40886, here are decompositions:

  • 3 + 40883 = 40886
  • 7 + 40879 = 40886
  • 19 + 40867 = 40886
  • 37 + 40849 = 40886
  • 67 + 40819 = 40886
  • 73 + 40813 = 40886
  • 127 + 40759 = 40886
  • 193 + 40693 = 40886

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40886 first appears in π at position 41,928 of the decimal expansion (the 41,928ordinal-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.
