Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550136, here are decompositions:

5 + 31550131 = 31550136
17 + 31550119 = 31550136
29 + 31550107 = 31550136
43 + 31550093 = 31550136
73 + 31550063 = 31550136
89 + 31550047 = 31550136
109 + 31550027 = 31550136
157 + 31549979 = 31550136

Showing the first eight; more decompositions exist.
