Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2736, here are decompositions:

  • 5 + 2731 = 2736
  • 7 + 2729 = 2736
  • 17 + 2719 = 2736
  • 23 + 2713 = 2736
  • 29 + 2707 = 2736
  • 37 + 2699 = 2736
  • 43 + 2693 = 2736
  • 47 + 2689 = 2736

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 2736 first appears in π at position 2,257 of the decimal expansion (the 2,257ordinal-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.
