Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583364, here are decompositions:

11 + 31583353 = 31583364
13 + 31583351 = 31583364
41 + 31583323 = 31583364
83 + 31583281 = 31583364
107 + 31583257 = 31583364
193 + 31583171 = 31583364
227 + 31583137 = 31583364
233 + 31583131 = 31583364

Showing the first eight; more decompositions exist.
