Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622226, here are decompositions:

19 + 31622207 = 31622226
37 + 31622189 = 31622226
43 + 31622183 = 31622226
47 + 31622179 = 31622226
59 + 31622167 = 31622226
73 + 31622153 = 31622226
79 + 31622147 = 31622226
107 + 31622119 = 31622226

Showing the first eight; more decompositions exist.
