Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622170, here are decompositions:

3 + 31622167 = 31622170
17 + 31622153 = 31622170
23 + 31622147 = 31622170
29 + 31622141 = 31622170
89 + 31622081 = 31622170
191 + 31621979 = 31622170
269 + 31621901 = 31622170
431 + 31621739 = 31622170

Showing the first eight; more decompositions exist.
