Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622550, here are decompositions:

13 + 31622537 = 31622550
31 + 31622519 = 31622550
41 + 31622509 = 31622550
59 + 31622491 = 31622550
83 + 31622467 = 31622550
173 + 31622377 = 31622550
181 + 31622369 = 31622550
257 + 31622293 = 31622550

Showing the first eight; more decompositions exist.
