Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25768, here are decompositions:

  • 5 + 25763 = 25768
  • 89 + 25679 = 25768
  • 101 + 25667 = 25768
  • 167 + 25601 = 25768
  • 179 + 25589 = 25768
  • 191 + 25577 = 25768
  • 227 + 25541 = 25768
  • 311 + 25457 = 25768

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 25768 first appears in π at position 11,619 of the decimal expansion (the 11,619ordinal-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.
