Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27656, here are decompositions:

  • 3 + 27653 = 27656
  • 73 + 27583 = 27656
  • 127 + 27529 = 27656
  • 199 + 27457 = 27656
  • 229 + 27427 = 27656
  • 373 + 27283 = 27656
  • 379 + 27277 = 27656
  • 397 + 27259 = 27656

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 27656 first appears in π at position 3,796 of the decimal expansion (the 3,796ordinal-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.
