Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8918, here are decompositions:

  • 31 + 8887 = 8918
  • 79 + 8839 = 8918
  • 97 + 8821 = 8918
  • 139 + 8779 = 8918
  • 157 + 8761 = 8918
  • 181 + 8737 = 8918
  • 199 + 8719 = 8918
  • 211 + 8707 = 8918

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 8918 first appears in π at position 12,962 of the decimal expansion (the 12,962ordinal-suffix:nd 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.
