Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3256, here are decompositions:

  • 3 + 3253 = 3256
  • 5 + 3251 = 3256
  • 47 + 3209 = 3256
  • 53 + 3203 = 3256
  • 89 + 3167 = 3256
  • 137 + 3119 = 3256
  • 167 + 3089 = 3256
  • 173 + 3083 = 3256

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 3256 first appears in π at position 7,417 of the decimal expansion (the 7,417ordinal-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.
