Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2176, here are decompositions:

  • 23 + 2153 = 2176
  • 47 + 2129 = 2176
  • 89 + 2087 = 2176
  • 107 + 2069 = 2176
  • 113 + 2063 = 2176
  • 137 + 2039 = 2176
  • 149 + 2027 = 2176
  • 173 + 2003 = 2176

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 2176 first appears in π at position 48,457 of the decimal expansion (the 48,457ordinal-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.
