Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622304, here are decompositions:

11 + 31622293 = 31622304
17 + 31622287 = 31622304
23 + 31622281 = 31622304
31 + 31622273 = 31622304
47 + 31622257 = 31622304
67 + 31622237 = 31622304
97 + 31622207 = 31622304
137 + 31622167 = 31622304

Showing the first eight; more decompositions exist.
