Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552932, here are decompositions:

13 + 31552919 = 31552932
41 + 31552891 = 31552932
53 + 31552879 = 31552932
79 + 31552853 = 31552932
101 + 31552831 = 31552932
199 + 31552733 = 31552932
211 + 31552721 = 31552932
223 + 31552709 = 31552932

Showing the first eight; more decompositions exist.
