Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22842, here are decompositions:

  • 31 + 22811 = 22842
  • 59 + 22783 = 22842
  • 73 + 22769 = 22842
  • 101 + 22741 = 22842
  • 103 + 22739 = 22842
  • 151 + 22691 = 22842
  • 163 + 22679 = 22842
  • 173 + 22669 = 22842

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 22842 first appears in π at position 97,788 of the decimal expansion (the 97,788ordinal-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.
