Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516498, here are decompositions:

5 + 31516493 = 31516498
29 + 31516469 = 31516498
71 + 31516427 = 31516498
137 + 31516361 = 31516498
179 + 31516319 = 31516498
257 + 31516241 = 31516498
359 + 31516139 = 31516498
389 + 31516109 = 31516498

Showing the first eight; more decompositions exist.
