Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550896, here are decompositions:

17 + 31550879 = 31550896
29 + 31550867 = 31550896
59 + 31550837 = 31550896
89 + 31550807 = 31550896
149 + 31550747 = 31550896
173 + 31550723 = 31550896
197 + 31550699 = 31550896
269 + 31550627 = 31550896

Showing the first eight; more decompositions exist.
