Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553088, here are decompositions:

11 + 31553077 = 31553088
19 + 31553069 = 31553088
67 + 31553021 = 31553088
71 + 31553017 = 31553088
89 + 31552999 = 31553088
181 + 31552907 = 31553088
197 + 31552891 = 31553088
241 + 31552847 = 31553088

Showing the first eight; more decompositions exist.
