Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523354, here are decompositions:

7 + 31523347 = 31523354
61 + 31523293 = 31523354
103 + 31523251 = 31523354
127 + 31523227 = 31523354
193 + 31523161 = 31523354
211 + 31523143 = 31523354
223 + 31523131 = 31523354
241 + 31523113 = 31523354

Showing the first eight; more decompositions exist.
