Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622190, here are decompositions:

7 + 31622183 = 31622190
11 + 31622179 = 31622190
23 + 31622167 = 31622190
37 + 31622153 = 31622190
43 + 31622147 = 31622190
59 + 31622131 = 31622190
71 + 31622119 = 31622190
109 + 31622081 = 31622190

Showing the first eight; more decompositions exist.
