Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589982, here are decompositions:

5 + 31589977 = 31589982
29 + 31589953 = 31589982
59 + 31589923 = 31589982
113 + 31589869 = 31589982
139 + 31589843 = 31589982
163 + 31589819 = 31589982
211 + 31589771 = 31589982
223 + 31589759 = 31589982

Showing the first eight; more decompositions exist.
