Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613022, here are decompositions:

31 + 31612991 = 31613022
41 + 31612981 = 31613022
53 + 31612969 = 31613022
61 + 31612961 = 31613022
71 + 31612951 = 31613022
83 + 31612939 = 31613022
109 + 31612913 = 31613022
131 + 31612891 = 31613022

Showing the first eight; more decompositions exist.
