Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622200, here are decompositions:

11 + 31622189 = 31622200
17 + 31622183 = 31622200
47 + 31622153 = 31622200
53 + 31622147 = 31622200
59 + 31622141 = 31622200
251 + 31621949 = 31622200
353 + 31621847 = 31622200
461 + 31621739 = 31622200

Showing the first eight; more decompositions exist.
