Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622966, here are decompositions:

7 + 31622959 = 31622966
19 + 31622947 = 31622966
43 + 31622923 = 31622966
73 + 31622893 = 31622966
103 + 31622863 = 31622966
157 + 31622809 = 31622966
163 + 31622803 = 31622966
223 + 31622743 = 31622966

Showing the first eight; more decompositions exist.
