Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13636, here are decompositions:

  • 3 + 13633 = 13636
  • 17 + 13619 = 13636
  • 23 + 13613 = 13636
  • 59 + 13577 = 13636
  • 83 + 13553 = 13636
  • 113 + 13523 = 13636
  • 137 + 13499 = 13636
  • 149 + 13487 = 13636

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13636 first appears in π at position 100,575 of the decimal expansion (the 100,575ordinal-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.
