Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522314, here are decompositions:

17 + 31522297 = 31522314
37 + 31522277 = 31522314
67 + 31522247 = 31522314
71 + 31522243 = 31522314
73 + 31522241 = 31522314
107 + 31522207 = 31522314
211 + 31522103 = 31522314
223 + 31522091 = 31522314

Showing the first eight; more decompositions exist.
