Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13790, here are decompositions:

  • 31 + 13759 = 13790
  • 61 + 13729 = 13790
  • 67 + 13723 = 13790
  • 79 + 13711 = 13790
  • 97 + 13693 = 13790
  • 103 + 13687 = 13790
  • 109 + 13681 = 13790
  • 157 + 13633 = 13790

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13790 first appears in π at position 156,650 of the decimal expansion (the 156,650ordinal-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.
