Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550342, here are decompositions:

3 + 31550339 = 31550342
13 + 31550329 = 31550342
163 + 31550179 = 31550342
193 + 31550149 = 31550342
211 + 31550131 = 31550342
223 + 31550119 = 31550342
379 + 31549963 = 31550342
409 + 31549933 = 31550342

Showing the first eight; more decompositions exist.
