Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556792, here are decompositions:

  • 13 + 31556779 = 31556792
  • 139 + 31556653 = 31556792
  • 313 + 31556479 = 31556792
  • 331 + 31556461 = 31556792
  • 439 + 31556353 = 31556792
  • 499 + 31556293 = 31556792
  • 643 + 31556149 = 31556792
  • 811 + 31555981 = 31556792

Showing the first eight; more decompositions exist.

Public, routable address (assignable to a host on the internet).

Position in π

The digit sequence 31556792 first appears in π at position 194,333 of the decimal expansion (the 194,333ordinal-suffix:rd 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.
