Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6842, here are decompositions:

  • 13 + 6829 = 6842
  • 19 + 6823 = 6842
  • 61 + 6781 = 6842
  • 79 + 6763 = 6842
  • 109 + 6733 = 6842
  • 139 + 6703 = 6842
  • 151 + 6691 = 6842
  • 163 + 6679 = 6842

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 6842 first appears in π at position 1,288 of the decimal expansion (the 1,288ordinal-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.
