Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622264, here are decompositions:

7 + 31622257 = 31622264
97 + 31622167 = 31622264
151 + 31622113 = 31622264
283 + 31621981 = 31622264
307 + 31621957 = 31622264
367 + 31621897 = 31622264
433 + 31621831 = 31622264
571 + 31621693 = 31622264

Showing the first eight; more decompositions exist.
