Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516282, here are decompositions:

29 + 31516253 = 31516282
41 + 31516241 = 31516282
173 + 31516109 = 31516282
179 + 31516103 = 31516282
293 + 31515989 = 31516282
383 + 31515899 = 31516282
389 + 31515893 = 31516282
401 + 31515881 = 31516282

Showing the first eight; more decompositions exist.
