Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617418, here are decompositions:

5 + 31617413 = 31617418
11 + 31617407 = 31617418
47 + 31617371 = 31617418
89 + 31617329 = 31617418
137 + 31617281 = 31617418
149 + 31617269 = 31617418
167 + 31617251 = 31617418
179 + 31617239 = 31617418

Showing the first eight; more decompositions exist.
