Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13822, here are decompositions:

  • 23 + 13799 = 13822
  • 41 + 13781 = 13822
  • 59 + 13763 = 13822
  • 71 + 13751 = 13822
  • 101 + 13721 = 13822
  • 113 + 13709 = 13822
  • 131 + 13691 = 13822
  • 173 + 13649 = 13822

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 13822 first appears in π at position 130,831 of the decimal expansion (the 130,831ordinal-suffix:st 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.
