Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552980, here are decompositions:

37 + 31552943 = 31552980
61 + 31552919 = 31552980
73 + 31552907 = 31552980
89 + 31552891 = 31552980
97 + 31552883 = 31552980
101 + 31552879 = 31552980
127 + 31552853 = 31552980
149 + 31552831 = 31552980

Showing the first eight; more decompositions exist.
