Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68770, here are decompositions:

  • 3 + 68767 = 68770
  • 41 + 68729 = 68770
  • 59 + 68711 = 68770
  • 71 + 68699 = 68770
  • 83 + 68687 = 68770
  • 101 + 68669 = 68770
  • 131 + 68639 = 68770
  • 137 + 68633 = 68770

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 68770 first appears in π at position 192,428 of the decimal expansion (the 192,428ordinal-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.
