Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583304, here are decompositions:

23 + 31583281 = 31583304
47 + 31583257 = 31583304
157 + 31583147 = 31583304
167 + 31583137 = 31583304
173 + 31583131 = 31583304
223 + 31583081 = 31583304
257 + 31583047 = 31583304
271 + 31583033 = 31583304

Showing the first eight; more decompositions exist.
