Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553272, here are decompositions:

11 + 31553261 = 31553272
53 + 31553219 = 31553272
59 + 31553213 = 31553272
71 + 31553201 = 31553272
89 + 31553183 = 31553272
251 + 31553021 = 31553272
353 + 31552919 = 31553272
389 + 31552883 = 31553272

Showing the first eight; more decompositions exist.
