Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552028, here are decompositions:

31 + 31551997 = 31552028
127 + 31551901 = 31552028
271 + 31551757 = 31552028
307 + 31551721 = 31552028
577 + 31551451 = 31552028
619 + 31551409 = 31552028
709 + 31551319 = 31552028
751 + 31551277 = 31552028

Showing the first eight; more decompositions exist.
