Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622518, here are decompositions:

89 + 31622429 = 31622518
149 + 31622369 = 31622518
281 + 31622237 = 31622518
311 + 31622207 = 31622518
569 + 31621949 = 31622518
617 + 31621901 = 31622518
839 + 31621679 = 31622518
857 + 31621661 = 31622518

Showing the first eight; more decompositions exist.
