Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552968, here are decompositions:

61 + 31552907 = 31552968
89 + 31552879 = 31552968
137 + 31552831 = 31552968
151 + 31552817 = 31552968
241 + 31552727 = 31552968
347 + 31552621 = 31552968
379 + 31552589 = 31552968
389 + 31552579 = 31552968

Showing the first eight; more decompositions exist.
