Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622222, here are decompositions:

43 + 31622179 = 31622222
103 + 31622119 = 31622222
109 + 31622113 = 31622222
241 + 31621981 = 31622222
571 + 31621651 = 31622222
601 + 31621621 = 31622222
631 + 31621591 = 31622222
661 + 31621561 = 31622222

Showing the first eight; more decompositions exist.
