Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73228, here are decompositions:

  • 47 + 73181 = 73228
  • 101 + 73127 = 73228
  • 107 + 73121 = 73228
  • 137 + 73091 = 73228
  • 149 + 73079 = 73228
  • 167 + 73061 = 73228
  • 191 + 73037 = 73228
  • 251 + 72977 = 73228

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 73228 first appears in π at position 79,612 of the decimal expansion (the 79,612ordinal-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.
