Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550276, here are decompositions:

19 + 31550257 = 31550276
97 + 31550179 = 31550276
127 + 31550149 = 31550276
139 + 31550137 = 31550276
157 + 31550119 = 31550276
229 + 31550047 = 31550276
313 + 31549963 = 31550276
379 + 31549897 = 31550276

Showing the first eight; more decompositions exist.
