Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558982, here are decompositions:

19 + 31558963 = 31558982
43 + 31558939 = 31558982
139 + 31558843 = 31558982
151 + 31558831 = 31558982
163 + 31558819 = 31558982
193 + 31558789 = 31558982
211 + 31558771 = 31558982
223 + 31558759 = 31558982

Showing the first eight; more decompositions exist.
