Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13718, here are decompositions:

  • 7 + 13711 = 13718
  • 31 + 13687 = 13718
  • 37 + 13681 = 13718
  • 127 + 13591 = 13718
  • 151 + 13567 = 13718
  • 181 + 13537 = 13718
  • 241 + 13477 = 13718
  • 277 + 13441 = 13718

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13718 first appears in π at position 15,824 of the decimal expansion (the 15,824ordinal-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.
