Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583338, here are decompositions:

167 + 31583171 = 31583338
179 + 31583159 = 31583338
191 + 31583147 = 31583338
251 + 31583087 = 31583338
257 + 31583081 = 31583338
389 + 31582949 = 31583338
401 + 31582937 = 31583338
431 + 31582907 = 31583338

Showing the first eight; more decompositions exist.
