Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12682, here are decompositions:

  • 11 + 12671 = 12682
  • 23 + 12659 = 12682
  • 29 + 12653 = 12682
  • 41 + 12641 = 12682
  • 71 + 12611 = 12682
  • 113 + 12569 = 12682
  • 179 + 12503 = 12682
  • 191 + 12491 = 12682

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12682 first appears in π at position 42,446 of the decimal expansion (the 42,446ordinal-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.
