Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550054, here are decompositions:

7 + 31550047 = 31550054
73 + 31549981 = 31550054
157 + 31549897 = 31550054
163 + 31549891 = 31550054
181 + 31549873 = 31550054
337 + 31549717 = 31550054
457 + 31549597 = 31550054
463 + 31549591 = 31550054

Showing the first eight; more decompositions exist.
