Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550246, here are decompositions:

67 + 31550179 = 31550246
97 + 31550149 = 31550246
109 + 31550137 = 31550246
127 + 31550119 = 31550246
139 + 31550107 = 31550246
199 + 31550047 = 31550246
283 + 31549963 = 31550246
313 + 31549933 = 31550246

Showing the first eight; more decompositions exist.
