Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550256, here are decompositions:

5 + 31550251 = 31550256
43 + 31550213 = 31550256
79 + 31550177 = 31550256
103 + 31550153 = 31550256
107 + 31550149 = 31550256
137 + 31550119 = 31550256
149 + 31550107 = 31550256
163 + 31550093 = 31550256

Showing the first eight; more decompositions exist.
