Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622250, here are decompositions:

13 + 31622237 = 31622250
43 + 31622207 = 31622250
61 + 31622189 = 31622250
67 + 31622183 = 31622250
71 + 31622179 = 31622250
83 + 31622167 = 31622250
97 + 31622153 = 31622250
103 + 31622147 = 31622250

Showing the first eight; more decompositions exist.
