Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552008, here are decompositions:

11 + 31551997 = 31552008
29 + 31551979 = 31552008
31 + 31551977 = 31552008
67 + 31551941 = 31552008
71 + 31551937 = 31552008
107 + 31551901 = 31552008
149 + 31551859 = 31552008
151 + 31551857 = 31552008

Showing the first eight; more decompositions exist.
