Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552004, here are decompositions:

7 + 31551997 = 31552004
67 + 31551937 = 31552004
103 + 31551901 = 31552004
151 + 31551853 = 31552004
223 + 31551781 = 31552004
271 + 31551733 = 31552004
283 + 31551721 = 31552004
457 + 31551547 = 31552004

Showing the first eight; more decompositions exist.
