Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13958, here are decompositions:

  • 37 + 13921 = 13958
  • 79 + 13879 = 13958
  • 127 + 13831 = 13958
  • 151 + 13807 = 13958
  • 199 + 13759 = 13958
  • 229 + 13729 = 13958
  • 271 + 13687 = 13958
  • 277 + 13681 = 13958

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 13958 first appears in π at position 95,998 of the decimal expansion (the 95,998ordinal-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.
