Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538022, here are decompositions:

23 + 31537999 = 31538022
41 + 31537981 = 31538022
83 + 31537939 = 31538022
101 + 31537921 = 31538022
151 + 31537871 = 31538022
163 + 31537859 = 31538022
179 + 31537843 = 31538022
199 + 31537823 = 31538022

Showing the first eight; more decompositions exist.
