Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1232, here are decompositions:

  • 3 + 1229 = 1232
  • 19 + 1213 = 1232
  • 31 + 1201 = 1232
  • 61 + 1171 = 1232
  • 79 + 1153 = 1232
  • 103 + 1129 = 1232
  • 109 + 1123 = 1232
  • 139 + 1093 = 1232

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 1232 first appears in π at position 6,548 of the decimal expansion (the 6,548ordinal-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.
