Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13930, here are decompositions:

  • 17 + 13913 = 13930
  • 23 + 13907 = 13930
  • 29 + 13901 = 13930
  • 47 + 13883 = 13930
  • 53 + 13877 = 13930
  • 71 + 13859 = 13930
  • 89 + 13841 = 13930
  • 101 + 13829 = 13930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13930 first appears in π at position 169,188 of the decimal expansion (the 169,188ordinal-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.
