Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23566, here are decompositions:

  • 3 + 23563 = 23566
  • 5 + 23561 = 23566
  • 17 + 23549 = 23566
  • 29 + 23537 = 23566
  • 107 + 23459 = 23566
  • 149 + 23417 = 23566
  • 167 + 23399 = 23566
  • 197 + 23369 = 23566

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 23566 first appears in π at position 191,218 of the decimal expansion (the 191,218ordinal-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.
