Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16450, here are decompositions:

  • 3 + 16447 = 16450
  • 17 + 16433 = 16450
  • 23 + 16427 = 16450
  • 29 + 16421 = 16450
  • 89 + 16361 = 16450
  • 101 + 16349 = 16450
  • 131 + 16319 = 16450
  • 149 + 16301 = 16450

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 16450 first appears in π at position 50,536 of the decimal expansion (the 50,536ordinal-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.
