Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51826, here are decompositions:

  • 23 + 51803 = 51826
  • 29 + 51797 = 51826
  • 59 + 51767 = 51826
  • 107 + 51719 = 51826
  • 113 + 51713 = 51826
  • 167 + 51659 = 51826
  • 179 + 51647 = 51826
  • 227 + 51599 = 51826

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 51826 first appears in π at position 46,527 of the decimal expansion (the 46,527ordinal-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.
