Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 14640, here are decompositions:

  • 7 + 14633 = 14640
  • 11 + 14629 = 14640
  • 13 + 14627 = 14640
  • 19 + 14621 = 14640
  • 47 + 14593 = 14640
  • 79 + 14561 = 14640
  • 83 + 14557 = 14640
  • 89 + 14551 = 14640

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 14640 first appears in π at position 174,503 of the decimal expansion (the 174,503ordinal-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.
