Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552950, here are decompositions:

7 + 31552943 = 31552950
31 + 31552919 = 31552950
43 + 31552907 = 31552950
59 + 31552891 = 31552950
67 + 31552883 = 31552950
71 + 31552879 = 31552950
97 + 31552853 = 31552950
103 + 31552847 = 31552950

Showing the first eight; more decompositions exist.
