Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65508, here are decompositions:

  • 11 + 65497 = 65508
  • 29 + 65479 = 65508
  • 59 + 65449 = 65508
  • 61 + 65447 = 65508
  • 71 + 65437 = 65508
  • 89 + 65419 = 65508
  • 101 + 65407 = 65508
  • 127 + 65381 = 65508

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 65508 first appears in π at position 24,678 of the decimal expansion (the 24,678ordinal-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.
