Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622214, here are decompositions:

7 + 31622207 = 31622214
31 + 31622183 = 31622214
47 + 31622167 = 31622214
61 + 31622153 = 31622214
67 + 31622147 = 31622214
73 + 31622141 = 31622214
83 + 31622131 = 31622214
101 + 31622113 = 31622214

Showing the first eight; more decompositions exist.
