Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30876, here are decompositions:

  • 5 + 30871 = 30876
  • 7 + 30869 = 30876
  • 17 + 30859 = 30876
  • 23 + 30853 = 30876
  • 37 + 30839 = 30876
  • 47 + 30829 = 30876
  • 59 + 30817 = 30876
  • 67 + 30809 = 30876

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 30876 first appears in π at position 173,831 of the decimal expansion (the 173,831ordinal-suffix:st 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.
