Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23508, here are decompositions:

  • 11 + 23497 = 23508
  • 61 + 23447 = 23508
  • 109 + 23399 = 23508
  • 137 + 23371 = 23508
  • 139 + 23369 = 23508
  • 151 + 23357 = 23508
  • 181 + 23327 = 23508
  • 197 + 23311 = 23508

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 23508 first appears in π at position 51,480 of the decimal expansion (the 51,480ordinal-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.
