Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622366, here are decompositions:

19 + 31622347 = 31622366
73 + 31622293 = 31622366
79 + 31622287 = 31622366
109 + 31622257 = 31622366
199 + 31622167 = 31622366
409 + 31621957 = 31622366
487 + 31621879 = 31622366
613 + 31621753 = 31622366

Showing the first eight; more decompositions exist.
