Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622588, here are decompositions:

79 + 31622509 = 31622588
97 + 31622491 = 31622588
199 + 31622389 = 31622588
211 + 31622377 = 31622588
241 + 31622347 = 31622588
307 + 31622281 = 31622588
331 + 31622257 = 31622588
409 + 31622179 = 31622588

Showing the first eight; more decompositions exist.
