Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516350, here are decompositions:

17 + 31516333 = 31516350
23 + 31516327 = 31516350
31 + 31516319 = 31516350
53 + 31516297 = 31516350
97 + 31516253 = 31516350
109 + 31516241 = 31516350
113 + 31516237 = 31516350
149 + 31516201 = 31516350

Showing the first eight; more decompositions exist.
