Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76680, here are decompositions:

  • 7 + 76673 = 76680
  • 13 + 76667 = 76680
  • 29 + 76651 = 76680
  • 31 + 76649 = 76680
  • 73 + 76607 = 76680
  • 83 + 76597 = 76680
  • 101 + 76579 = 76680
  • 137 + 76543 = 76680

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76680 first appears in π at position 145,673 of the decimal expansion (the 145,673ordinal-suffix:rd 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.
