Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532262, here are decompositions:

43 + 31532219 = 31532262
53 + 31532209 = 31532262
59 + 31532203 = 31532262
149 + 31532113 = 31532262
173 + 31532089 = 31532262
191 + 31532071 = 31532262
199 + 31532063 = 31532262
241 + 31532021 = 31532262

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.
