Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622508, here are decompositions:

17 + 31622491 = 31622508
41 + 31622467 = 31622508
79 + 31622429 = 31622508
131 + 31622377 = 31622508
139 + 31622369 = 31622508
227 + 31622281 = 31622508
251 + 31622257 = 31622508
271 + 31622237 = 31622508

Showing the first eight; more decompositions exist.
