Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523416, here are decompositions:

5 + 31523411 = 31523416
17 + 31523399 = 31523416
107 + 31523309 = 31523416
137 + 31523279 = 31523416
149 + 31523267 = 31523416
173 + 31523243 = 31523416
179 + 31523237 = 31523416
317 + 31523099 = 31523416

Showing the first eight; more decompositions exist.
