Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40536, here are decompositions:

  • 5 + 40531 = 40536
  • 7 + 40529 = 40536
  • 17 + 40519 = 40536
  • 29 + 40507 = 40536
  • 37 + 40499 = 40536
  • 43 + 40493 = 40536
  • 53 + 40483 = 40536
  • 103 + 40433 = 40536

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 40536 first appears in π at position 186,344 of the decimal expansion (the 186,344ordinal-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.
