Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516708, here are decompositions:

5 + 31516703 = 31516708
11 + 31516697 = 31516708
89 + 31516619 = 31516708
137 + 31516571 = 31516708
149 + 31516559 = 31516708
239 + 31516469 = 31516708
281 + 31516427 = 31516708
347 + 31516361 = 31516708

Showing the first eight; more decompositions exist.
