Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583316, here are decompositions:

47 + 31583269 = 31583316
59 + 31583257 = 31583316
157 + 31583159 = 31583316
179 + 31583137 = 31583316
229 + 31583087 = 31583316
269 + 31583047 = 31583316
283 + 31583033 = 31583316
293 + 31583023 = 31583316

Showing the first eight; more decompositions exist.
