Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583698, here are decompositions:

5 + 31583693 = 31583698
11 + 31583687 = 31583698
71 + 31583627 = 31583698
101 + 31583597 = 31583698
137 + 31583561 = 31583698
149 + 31583549 = 31583698
191 + 31583507 = 31583698
347 + 31583351 = 31583698

Showing the first eight; more decompositions exist.
