Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18056, here are decompositions:

  • 7 + 18049 = 18056
  • 13 + 18043 = 18056
  • 43 + 18013 = 18056
  • 67 + 17989 = 18056
  • 79 + 17977 = 18056
  • 97 + 17959 = 18056
  • 127 + 17929 = 18056
  • 193 + 17863 = 18056

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18056 first appears in π at position 383,960 of the decimal expansion (the 383,960ordinal-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.
