Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550076, here are decompositions:

13 + 31550063 = 31550076
29 + 31550047 = 31550076
97 + 31549979 = 31550076
109 + 31549967 = 31550076
113 + 31549963 = 31550076
157 + 31549919 = 31550076
179 + 31549897 = 31550076
197 + 31549879 = 31550076

Showing the first eight; more decompositions exist.
