Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516366, here are decompositions:

5 + 31516361 = 31516366
47 + 31516319 = 31516366
113 + 31516253 = 31516366
227 + 31516139 = 31516366
257 + 31516109 = 31516366
263 + 31516103 = 31516366
359 + 31516007 = 31516366
467 + 31515899 = 31516366

Showing the first eight; more decompositions exist.
