Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617272, here are decompositions:

3 + 31617269 = 31617272
19 + 31617253 = 31617272
73 + 31617199 = 31617272
139 + 31617133 = 31617272
199 + 31617073 = 31617272
223 + 31617049 = 31617272
433 + 31616839 = 31617272
499 + 31616773 = 31617272

Showing the first eight; more decompositions exist.
