Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583418, here are decompositions:

5 + 31583413 = 31583418
67 + 31583351 = 31583418
137 + 31583281 = 31583418
149 + 31583269 = 31583418
271 + 31583147 = 31583418
281 + 31583137 = 31583418
331 + 31583087 = 31583418
337 + 31583081 = 31583418

Showing the first eight; more decompositions exist.
