Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12884, here are decompositions:

  • 31 + 12853 = 12884
  • 43 + 12841 = 12884
  • 61 + 12823 = 12884
  • 103 + 12781 = 12884
  • 127 + 12757 = 12884
  • 163 + 12721 = 12884
  • 181 + 12703 = 12884
  • 271 + 12613 = 12884

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12884 first appears in π at position 121,755 of the decimal expansion (the 121,755ordinal-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.
