Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622254, here are decompositions:

17 + 31622237 = 31622254
47 + 31622207 = 31622254
71 + 31622183 = 31622254
101 + 31622153 = 31622254
107 + 31622147 = 31622254
113 + 31622141 = 31622254
173 + 31622081 = 31622254
353 + 31621901 = 31622254

Showing the first eight; more decompositions exist.
