Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583752, here are decompositions:

3 + 31583749 = 31583752
23 + 31583729 = 31583752
59 + 31583693 = 31583752
89 + 31583663 = 31583752
131 + 31583621 = 31583752
191 + 31583561 = 31583752
401 + 31583351 = 31583752
593 + 31583159 = 31583752

Showing the first eight; more decompositions exist.
