Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622168, here are decompositions:

37 + 31622131 = 31622168
211 + 31621957 = 31622168
271 + 31621897 = 31622168
337 + 31621831 = 31622168
499 + 31621669 = 31622168
547 + 31621621 = 31622168
577 + 31621591 = 31622168
607 + 31621561 = 31622168

Showing the first eight; more decompositions exist.
