Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15716, here are decompositions:

  • 37 + 15679 = 15716
  • 67 + 15649 = 15716
  • 73 + 15643 = 15716
  • 97 + 15619 = 15716
  • 109 + 15607 = 15716
  • 157 + 15559 = 15716
  • 223 + 15493 = 15716
  • 277 + 15439 = 15716

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15716 first appears in π at position 235,082 of the decimal expansion (the 235,082ordinal-suffix:nd 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.
