Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80786, here are decompositions:

  • 3 + 80783 = 80786
  • 7 + 80779 = 80786
  • 37 + 80749 = 80786
  • 73 + 80713 = 80786
  • 103 + 80683 = 80786
  • 109 + 80677 = 80786
  • 157 + 80629 = 80786
  • 229 + 80557 = 80786

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80786 first appears in π at position 254,969 of the decimal expansion (the 254,969ordinal-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.
