Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622330, here are decompositions:

37 + 31622293 = 31622330
43 + 31622287 = 31622330
73 + 31622257 = 31622330
151 + 31622179 = 31622330
163 + 31622167 = 31622330
199 + 31622131 = 31622330
211 + 31622119 = 31622330
283 + 31622047 = 31622330

Showing the first eight; more decompositions exist.
