Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23168, here are decompositions:

  • 37 + 23131 = 23168
  • 97 + 23071 = 23168
  • 109 + 23059 = 23168
  • 127 + 23041 = 23168
  • 139 + 23029 = 23168
  • 151 + 23017 = 23168
  • 157 + 23011 = 23168
  • 307 + 22861 = 23168

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 23168 first appears in π at position 200,062 of the decimal expansion (the 200,062ordinal-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.
