Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66516, here are decompositions:

  • 7 + 66509 = 66516
  • 17 + 66499 = 66516
  • 53 + 66463 = 66516
  • 59 + 66457 = 66516
  • 67 + 66449 = 66516
  • 103 + 66413 = 66516
  • 113 + 66403 = 66516
  • 139 + 66377 = 66516

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66516 first appears in π at position 23,290 of the decimal expansion (the 23,290ordinal-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.
