Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589922, here are decompositions:

31 + 31589891 = 31589922
53 + 31589869 = 31589922
61 + 31589861 = 31589922
79 + 31589843 = 31589922
103 + 31589819 = 31589922
149 + 31589773 = 31589922
151 + 31589771 = 31589922
163 + 31589759 = 31589922

Showing the first eight; more decompositions exist.
