Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19350, here are decompositions:

  • 17 + 19333 = 19350
  • 31 + 19319 = 19350
  • 41 + 19309 = 19350
  • 61 + 19289 = 19350
  • 83 + 19267 = 19350
  • 101 + 19249 = 19350
  • 113 + 19237 = 19350
  • 131 + 19219 = 19350

Showing the first eight; more decompositions exist.

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.

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 19350 first appears in π at position 85,063 of the decimal expansion (the 85,063ordinal-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.
