Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13392, here are decompositions:

  • 11 + 13381 = 13392
  • 53 + 13339 = 13392
  • 61 + 13331 = 13392
  • 79 + 13313 = 13392
  • 83 + 13309 = 13392
  • 101 + 13291 = 13392
  • 151 + 13241 = 13392
  • 163 + 13229 = 13392

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13392 first appears in π at position 40,519 of the decimal expansion (the 40,519ordinal-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.
