Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13776, here are decompositions:

  • 13 + 13763 = 13776
  • 17 + 13759 = 13776
  • 19 + 13757 = 13776
  • 47 + 13729 = 13776
  • 53 + 13723 = 13776
  • 67 + 13709 = 13776
  • 79 + 13697 = 13776
  • 83 + 13693 = 13776

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13776 first appears in π at position 6,461 of the decimal expansion (the 6,461ordinal-suffix:st 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.
