Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13616, here are decompositions:

  • 3 + 13613 = 13616
  • 19 + 13597 = 13616
  • 79 + 13537 = 13616
  • 103 + 13513 = 13616
  • 139 + 13477 = 13616
  • 199 + 13417 = 13616
  • 277 + 13339 = 13616
  • 307 + 13309 = 13616

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13616 first appears in π at position 112,634 of the decimal expansion (the 112,634ordinal-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.
