Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552930, here are decompositions:

11 + 31552919 = 31552930
23 + 31552907 = 31552930
47 + 31552883 = 31552930
83 + 31552847 = 31552930
113 + 31552817 = 31552930
197 + 31552733 = 31552930
443 + 31552487 = 31552930
509 + 31552421 = 31552930

Showing the first eight; more decompositions exist.
