Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16256, here are decompositions:

  • 3 + 16253 = 16256
  • 7 + 16249 = 16256
  • 67 + 16189 = 16256
  • 73 + 16183 = 16256
  • 193 + 16063 = 16256
  • 199 + 16057 = 16256
  • 223 + 16033 = 16256
  • 283 + 15973 = 16256

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 16256 first appears in π at position 79,679 of the decimal expansion (the 79,679ordinal-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.
