Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622558, here are decompositions:

67 + 31622491 = 31622558
181 + 31622377 = 31622558
211 + 31622347 = 31622558
271 + 31622287 = 31622558
277 + 31622281 = 31622558
379 + 31622179 = 31622558
439 + 31622119 = 31622558
577 + 31621981 = 31622558

Showing the first eight; more decompositions exist.
