Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523414, here are decompositions:

3 + 31523411 = 31523414
7 + 31523407 = 31523414
67 + 31523347 = 31523414
163 + 31523251 = 31523414
193 + 31523221 = 31523414
271 + 31523143 = 31523414
283 + 31523131 = 31523414
463 + 31522951 = 31523414

Showing the first eight; more decompositions exist.
