Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622954, here are decompositions:

3 + 31622951 = 31622954
7 + 31622947 = 31622954
31 + 31622923 = 31622954
61 + 31622893 = 31622954
73 + 31622881 = 31622954
151 + 31622803 = 31622954
211 + 31622743 = 31622954
241 + 31622713 = 31622954

Showing the first eight; more decompositions exist.
