Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505896, here are decompositions:

53 + 31505843 = 31505896
83 + 31505813 = 31505896
89 + 31505807 = 31505896
113 + 31505783 = 31505896
167 + 31505729 = 31505896
173 + 31505723 = 31505896
239 + 31505657 = 31505896
263 + 31505633 = 31505896

Showing the first eight; more decompositions exist.
