Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553134, here are decompositions:

71 + 31553063 = 31553134
113 + 31553021 = 31553134
191 + 31552943 = 31553134
227 + 31552907 = 31553134
251 + 31552883 = 31553134
281 + 31552853 = 31553134
317 + 31552817 = 31553134
401 + 31552733 = 31553134

Showing the first eight; more decompositions exist.
