Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6512, here are decompositions:

  • 31 + 6481 = 6512
  • 43 + 6469 = 6512
  • 61 + 6451 = 6512
  • 139 + 6373 = 6512
  • 151 + 6361 = 6512
  • 211 + 6301 = 6512
  • 241 + 6271 = 6512
  • 283 + 6229 = 6512

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 6512 first appears in π at position 5,180 of the decimal expansion (the 5,180ordinal-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.
