Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622294, here are decompositions:

7 + 31622287 = 31622294
13 + 31622281 = 31622294
37 + 31622257 = 31622294
127 + 31622167 = 31622294
163 + 31622131 = 31622294
181 + 31622113 = 31622294
313 + 31621981 = 31622294
331 + 31621963 = 31622294

Showing the first eight; more decompositions exist.
