Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550268, here are decompositions:

11 + 31550257 = 31550268
17 + 31550251 = 31550268
47 + 31550221 = 31550268
67 + 31550201 = 31550268
89 + 31550179 = 31550268
131 + 31550137 = 31550268
137 + 31550131 = 31550268
149 + 31550119 = 31550268

Showing the first eight; more decompositions exist.
