Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622216, here are decompositions:

37 + 31622179 = 31622216
97 + 31622119 = 31622216
103 + 31622113 = 31622216
337 + 31621879 = 31622216
463 + 31621753 = 31622216
523 + 31621693 = 31622216
547 + 31621669 = 31622216
709 + 31621507 = 31622216

Showing the first eight; more decompositions exist.
