Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542294, here are decompositions:

13 + 31542281 = 31542294
61 + 31542233 = 31542294
97 + 31542197 = 31542294
131 + 31542163 = 31542294
181 + 31542113 = 31542294
191 + 31542103 = 31542294
211 + 31542083 = 31542294
227 + 31542067 = 31542294

Showing the first eight; more decompositions exist.

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.
