Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64004, here are decompositions:

  • 7 + 63997 = 64004
  • 97 + 63907 = 64004
  • 103 + 63901 = 64004
  • 151 + 63853 = 64004
  • 163 + 63841 = 64004
  • 181 + 63823 = 64004
  • 211 + 63793 = 64004
  • 223 + 63781 = 64004

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 64004 first appears in π at position 5,091 of the decimal expansion (the 5,091ordinal-suffix:st 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.
