Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42822, here are decompositions:

  • 29 + 42793 = 42822
  • 71 + 42751 = 42822
  • 79 + 42743 = 42822
  • 103 + 42719 = 42822
  • 113 + 42709 = 42822
  • 139 + 42683 = 42822
  • 173 + 42649 = 42822
  • 179 + 42643 = 42822

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 42822 first appears in π at position 5,616 of the decimal expansion (the 5,616ordinal-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.
