Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583668, here are decompositions:

5 + 31583663 = 31583668
41 + 31583627 = 31583668
47 + 31583621 = 31583668
71 + 31583597 = 31583668
107 + 31583561 = 31583668
191 + 31583477 = 31583668
317 + 31583351 = 31583668
509 + 31583159 = 31583668

Showing the first eight; more decompositions exist.
