Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622340, here are decompositions:

47 + 31622293 = 31622340
53 + 31622287 = 31622340
59 + 31622281 = 31622340
67 + 31622273 = 31622340
83 + 31622257 = 31622340
103 + 31622237 = 31622340
151 + 31622189 = 31622340
157 + 31622183 = 31622340

Showing the first eight; more decompositions exist.
