Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622310, here are decompositions:

17 + 31622293 = 31622310
23 + 31622287 = 31622310
29 + 31622281 = 31622310
37 + 31622273 = 31622310
53 + 31622257 = 31622310
73 + 31622237 = 31622310
103 + 31622207 = 31622310
127 + 31622183 = 31622310

Showing the first eight; more decompositions exist.
