Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446, here are decompositions:

  • 53 + 31393 = 31446
  • 59 + 31387 = 31446
  • 67 + 31379 = 31446
  • 89 + 31357 = 31446
  • 109 + 31337 = 31446
  • 113 + 31333 = 31446
  • 127 + 31319 = 31446
  • 139 + 31307 = 31446

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31446 first appears in π at position 14,649 of the decimal expansion (the 14,649ordinal-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.
