Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31354, here are decompositions:

  • 17 + 31337 = 31354
  • 47 + 31307 = 31354
  • 83 + 31271 = 31354
  • 101 + 31253 = 31354
  • 107 + 31247 = 31354
  • 131 + 31223 = 31354
  • 173 + 31181 = 31354
  • 233 + 31121 = 31354

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 31354 first appears in π at position 481,909 of the decimal expansion (the 481,909ordinal-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.
