Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583298, here are decompositions:

17 + 31583281 = 31583298
29 + 31583269 = 31583298
41 + 31583257 = 31583298
127 + 31583171 = 31583298
139 + 31583159 = 31583298
151 + 31583147 = 31583298
167 + 31583131 = 31583298
211 + 31583087 = 31583298

Showing the first eight; more decompositions exist.
