Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81076, here are decompositions:

  • 5 + 81071 = 81076
  • 29 + 81047 = 81076
  • 53 + 81023 = 81076
  • 59 + 81017 = 81076
  • 113 + 80963 = 81076
  • 167 + 80909 = 81076
  • 179 + 80897 = 81076
  • 227 + 80849 = 81076

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 81076 first appears in π at position 96,715 of the decimal expansion (the 96,715ordinal-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.
