Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553284, here are decompositions:

5 + 31553279 = 31553284
11 + 31553273 = 31553284
23 + 31553261 = 31553284
71 + 31553213 = 31553284
83 + 31553201 = 31553284
101 + 31553183 = 31553284
107 + 31553177 = 31553284
263 + 31553021 = 31553284

Showing the first eight; more decompositions exist.
