Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15736, here are decompositions:

  • 3 + 15733 = 15736
  • 5 + 15731 = 15736
  • 53 + 15683 = 15736
  • 89 + 15647 = 15736
  • 107 + 15629 = 15736
  • 167 + 15569 = 15736
  • 239 + 15497 = 15736
  • 263 + 15473 = 15736

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 15736 first appears in π at position 189,737 of the decimal expansion (the 189,737ordinal-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.
