Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552984, here are decompositions:

41 + 31552943 = 31552984
101 + 31552883 = 31552984
131 + 31552853 = 31552984
137 + 31552847 = 31552984
167 + 31552817 = 31552984
251 + 31552733 = 31552984
257 + 31552727 = 31552984
263 + 31552721 = 31552984

Showing the first eight; more decompositions exist.
