Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516300, here are decompositions:

3 + 31516297 = 31516300
47 + 31516253 = 31516300
59 + 31516241 = 31516300
191 + 31516109 = 31516300
197 + 31516103 = 31516300
239 + 31516061 = 31516300
293 + 31516007 = 31516300
311 + 31515989 = 31516300

Showing the first eight; more decompositions exist.
