Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582248, here are decompositions:

7 + 31582241 = 31582248
31 + 31582217 = 31582248
41 + 31582207 = 31582248
127 + 31582121 = 31582248
151 + 31582097 = 31582248
199 + 31582049 = 31582248
211 + 31582037 = 31582248
227 + 31582021 = 31582248

Showing the first eight; more decompositions exist.
