Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622396, here are decompositions:

7 + 31622389 = 31622396
19 + 31622377 = 31622396
103 + 31622293 = 31622396
109 + 31622287 = 31622396
139 + 31622257 = 31622396
229 + 31622167 = 31622396
277 + 31622119 = 31622396
283 + 31622113 = 31622396

Showing the first eight; more decompositions exist.
