Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583982, here are decompositions:

11 + 31583971 = 31583982
41 + 31583941 = 31583982
61 + 31583921 = 31583982
71 + 31583911 = 31583982
151 + 31583831 = 31583982
163 + 31583819 = 31583982
173 + 31583809 = 31583982
179 + 31583803 = 31583982

Showing the first eight; more decompositions exist.
