Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622568, here are decompositions:

31 + 31622537 = 31622568
59 + 31622509 = 31622568
101 + 31622467 = 31622568
139 + 31622429 = 31622568
179 + 31622389 = 31622568
191 + 31622377 = 31622568
199 + 31622369 = 31622568
281 + 31622287 = 31622568

Showing the first eight; more decompositions exist.
