Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80860, here are decompositions:

  • 11 + 80849 = 80860
  • 29 + 80831 = 80860
  • 41 + 80819 = 80860
  • 71 + 80789 = 80860
  • 83 + 80777 = 80860
  • 113 + 80747 = 80860
  • 173 + 80687 = 80860
  • 179 + 80681 = 80860

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80860 first appears in π at position 76,098 of the decimal expansion (the 76,098ordinal-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.
