Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13624, here are decompositions:

  • 5 + 13619 = 13624
  • 11 + 13613 = 13624
  • 47 + 13577 = 13624
  • 71 + 13553 = 13624
  • 101 + 13523 = 13624
  • 137 + 13487 = 13624
  • 167 + 13457 = 13624
  • 173 + 13451 = 13624

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13624 first appears in π at position 318,368 of the decimal expansion (the 318,368ordinal-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.
