Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23210, here are decompositions:

  • 7 + 23203 = 23210
  • 13 + 23197 = 23210
  • 37 + 23173 = 23210
  • 43 + 23167 = 23210
  • 67 + 23143 = 23210
  • 79 + 23131 = 23210
  • 139 + 23071 = 23210
  • 151 + 23059 = 23210

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 23210 first appears in π at position 64,555 of the decimal expansion (the 64,555ordinal-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.
