Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15448, here are decompositions:

  • 5 + 15443 = 15448
  • 47 + 15401 = 15448
  • 71 + 15377 = 15448
  • 89 + 15359 = 15448
  • 149 + 15299 = 15448
  • 179 + 15269 = 15448
  • 311 + 15137 = 15448
  • 317 + 15131 = 15448

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 15448 first appears in π at position 48,953 of the decimal expansion (the 48,953ordinal-suffix:rd 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.
