Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12528, here are decompositions:

  • 11 + 12517 = 12528
  • 17 + 12511 = 12528
  • 31 + 12497 = 12528
  • 37 + 12491 = 12528
  • 41 + 12487 = 12528
  • 71 + 12457 = 12528
  • 107 + 12421 = 12528
  • 127 + 12401 = 12528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12528 first appears in π at position 29,972 of the decimal expansion (the 29,972ordinal-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.
