Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39312, here are decompositions:

  • 11 + 39301 = 39312
  • 19 + 39293 = 39312
  • 61 + 39251 = 39312
  • 71 + 39241 = 39312
  • 73 + 39239 = 39312
  • 79 + 39233 = 39312
  • 83 + 39229 = 39312
  • 103 + 39209 = 39312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39312 first appears in π at position 393,114 of the decimal expansion (the 393,114ordinal-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.
