Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15396, here are decompositions:

  • 5 + 15391 = 15396
  • 13 + 15383 = 15396
  • 19 + 15377 = 15396
  • 23 + 15373 = 15396
  • 37 + 15359 = 15396
  • 47 + 15349 = 15396
  • 67 + 15329 = 15396
  • 83 + 15313 = 15396

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 15396 first appears in π at position 26,399 of the decimal expansion (the 26,399ordinal-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.
