Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583704, here are decompositions:

3 + 31583701 = 31583704
11 + 31583693 = 31583704
17 + 31583687 = 31583704
41 + 31583663 = 31583704
71 + 31583633 = 31583704
83 + 31583621 = 31583704
107 + 31583597 = 31583704
197 + 31583507 = 31583704

Showing the first eight; more decompositions exist.
