Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533106, here are decompositions:

5 + 31533101 = 31533106
107 + 31532999 = 31533106
167 + 31532939 = 31533106
233 + 31532873 = 31533106
239 + 31532867 = 31533106
419 + 31532687 = 31533106
467 + 31532639 = 31533106
509 + 31532597 = 31533106

Showing the first eight; more decompositions exist.

IPv4 address

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
