Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15676, here are decompositions:

  • 5 + 15671 = 15676
  • 29 + 15647 = 15676
  • 47 + 15629 = 15676
  • 107 + 15569 = 15676
  • 149 + 15527 = 15676
  • 179 + 15497 = 15676
  • 233 + 15443 = 15676
  • 263 + 15413 = 15676

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15676 first appears in π at position 61,631 of the decimal expansion (the 61,631ordinal-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.
