Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71136, here are decompositions:

  • 7 + 71129 = 71136
  • 17 + 71119 = 71136
  • 47 + 71089 = 71136
  • 67 + 71069 = 71136
  • 97 + 71039 = 71136
  • 113 + 71023 = 71136
  • 137 + 70999 = 71136
  • 139 + 70997 = 71136

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 71136 first appears in π at position 183,044 of the decimal expansion (the 183,044ordinal-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.
