Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17938, here are decompositions:

  • 17 + 17921 = 17938
  • 29 + 17909 = 17938
  • 47 + 17891 = 17938
  • 101 + 17837 = 17938
  • 131 + 17807 = 17938
  • 149 + 17789 = 17938
  • 191 + 17747 = 17938
  • 257 + 17681 = 17938

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 17938 first appears in π at position 183,255 of the decimal expansion (the 183,255ordinal-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.
