Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583708, here are decompositions:

7 + 31583701 = 31583708
67 + 31583641 = 31583708
181 + 31583527 = 31583708
199 + 31583509 = 31583708
271 + 31583437 = 31583708
439 + 31583269 = 31583708
571 + 31583137 = 31583708
577 + 31583131 = 31583708

Showing the first eight; more decompositions exist.
