Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550284, here are decompositions:

71 + 31550213 = 31550284
83 + 31550201 = 31550284
107 + 31550177 = 31550284
131 + 31550153 = 31550284
173 + 31550111 = 31550284
191 + 31550093 = 31550284
257 + 31550027 = 31550284
263 + 31550021 = 31550284

Showing the first eight; more decompositions exist.
