Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622406, here are decompositions:

17 + 31622389 = 31622406
29 + 31622377 = 31622406
37 + 31622369 = 31622406
59 + 31622347 = 31622406
113 + 31622293 = 31622406
149 + 31622257 = 31622406
199 + 31622207 = 31622406
223 + 31622183 = 31622406

Showing the first eight; more decompositions exist.
