Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13576, here are decompositions:

  • 23 + 13553 = 13576
  • 53 + 13523 = 13576
  • 89 + 13487 = 13576
  • 107 + 13469 = 13576
  • 113 + 13463 = 13576
  • 179 + 13397 = 13576
  • 239 + 13337 = 13576
  • 263 + 13313 = 13576

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 13576 first appears in π at position 50,542 of the decimal expansion (the 50,542ordinal-suffix:nd 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.
