Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550234, here are decompositions:

13 + 31550221 = 31550234
97 + 31550137 = 31550234
103 + 31550131 = 31550234
127 + 31550107 = 31550234
271 + 31549963 = 31550234
337 + 31549897 = 31550234
433 + 31549801 = 31550234
571 + 31549663 = 31550234

Showing the first eight; more decompositions exist.
