Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550226, here are decompositions:

5 + 31550221 = 31550226
13 + 31550213 = 31550226
47 + 31550179 = 31550226
73 + 31550153 = 31550226
89 + 31550137 = 31550226
107 + 31550119 = 31550226
163 + 31550063 = 31550226
179 + 31550047 = 31550226

Showing the first eight; more decompositions exist.
