Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27782, here are decompositions:

  • 3 + 27779 = 27782
  • 19 + 27763 = 27782
  • 31 + 27751 = 27782
  • 43 + 27739 = 27782
  • 109 + 27673 = 27782
  • 151 + 27631 = 27782
  • 199 + 27583 = 27782
  • 241 + 27541 = 27782

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 27782 first appears in π at position 46,570 of the decimal expansion (the 46,570ordinal-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.
