Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617316, here are decompositions:

23 + 31617293 = 31617316
47 + 31617269 = 31617316
149 + 31617167 = 31617316
167 + 31617149 = 31617316
239 + 31617077 = 31617316
293 + 31617023 = 31617316
317 + 31616999 = 31617316
383 + 31616933 = 31617316

Showing the first eight; more decompositions exist.
