Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626454, here are decompositions:

  • 17 + 31626437 = 31626454
  • 47 + 31626407 = 31626454
  • 71 + 31626383 = 31626454
  • 131 + 31626323 = 31626454
  • 257 + 31626197 = 31626454
  • 263 + 31626191 = 31626454
  • 401 + 31626053 = 31626454
  • 443 + 31626011 = 31626454

Showing the first eight; more decompositions exist.

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

Position in π

The digit sequence 31626454 first appears in π at position 682,050 of the decimal expansion (the 682,050ordinal-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.
