Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65660, here are decompositions:

  • 3 + 65657 = 65660
  • 13 + 65647 = 65660
  • 31 + 65629 = 65660
  • 43 + 65617 = 65660
  • 61 + 65599 = 65660
  • 73 + 65587 = 65660
  • 79 + 65581 = 65660
  • 97 + 65563 = 65660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65660 first appears in π at position 282,261 of the decimal expansion (the 282,261ordinal-suffix:st 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.
