Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550184, here are decompositions:

5 + 31550179 = 31550184
7 + 31550177 = 31550184
31 + 31550153 = 31550184
47 + 31550137 = 31550184
53 + 31550131 = 31550184
73 + 31550111 = 31550184
137 + 31550047 = 31550184
157 + 31550027 = 31550184

Showing the first eight; more decompositions exist.
