Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13146, here are decompositions:

  • 19 + 13127 = 13146
  • 37 + 13109 = 13146
  • 43 + 13103 = 13146
  • 47 + 13099 = 13146
  • 53 + 13093 = 13146
  • 83 + 13063 = 13146
  • 97 + 13049 = 13146
  • 103 + 13043 = 13146

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13146 first appears in π at position 12,915 of the decimal expansion (the 12,915ordinal-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.
