Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553022, here are decompositions:

5 + 31553017 = 31553022
23 + 31552999 = 31553022
79 + 31552943 = 31553022
103 + 31552919 = 31553022
131 + 31552891 = 31553022
139 + 31552883 = 31553022
191 + 31552831 = 31553022
313 + 31552709 = 31553022

Showing the first eight; more decompositions exist.
