Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553058, here are decompositions:

37 + 31553021 = 31553058
41 + 31553017 = 31553058
59 + 31552999 = 31553058
139 + 31552919 = 31553058
151 + 31552907 = 31553058
167 + 31552891 = 31553058
179 + 31552879 = 31553058
211 + 31552847 = 31553058

Showing the first eight; more decompositions exist.
