Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550088, here are decompositions:

41 + 31550047 = 31550088
61 + 31550027 = 31550088
67 + 31550021 = 31550088
107 + 31549981 = 31550088
109 + 31549979 = 31550088
191 + 31549897 = 31550088
197 + 31549891 = 31550088
307 + 31549781 = 31550088

Showing the first eight; more decompositions exist.
