Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553304, here are decompositions:

31 + 31553273 = 31553304
43 + 31553261 = 31553304
71 + 31553233 = 31553304
103 + 31553201 = 31553304
127 + 31553177 = 31553304
227 + 31553077 = 31553304
241 + 31553063 = 31553304
283 + 31553021 = 31553304

Showing the first eight; more decompositions exist.
