Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583964, here are decompositions:

23 + 31583941 = 31583964
43 + 31583921 = 31583964
53 + 31583911 = 31583964
67 + 31583897 = 31583964
101 + 31583863 = 31583964
107 + 31583857 = 31583964
127 + 31583837 = 31583964
193 + 31583771 = 31583964

Showing the first eight; more decompositions exist.
