Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63966, here are decompositions:

  • 17 + 63949 = 63966
  • 37 + 63929 = 63966
  • 53 + 63913 = 63966
  • 59 + 63907 = 63966
  • 103 + 63863 = 63966
  • 109 + 63857 = 63966
  • 113 + 63853 = 63966
  • 127 + 63839 = 63966

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 63966 first appears in π at position 26,519 of the decimal expansion (the 26,519ordinal-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.
