Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553032, here are decompositions:

11 + 31553021 = 31553032
89 + 31552943 = 31553032
113 + 31552919 = 31553032
149 + 31552883 = 31553032
179 + 31552853 = 31553032
311 + 31552721 = 31553032
389 + 31552643 = 31553032
443 + 31552589 = 31553032

Showing the first eight; more decompositions exist.
