Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583712, here are decompositions:

11 + 31583701 = 31583712
19 + 31583693 = 31583712
53 + 31583659 = 31583712
71 + 31583641 = 31583712
79 + 31583633 = 31583712
151 + 31583561 = 31583712
163 + 31583549 = 31583712
191 + 31583521 = 31583712

Showing the first eight; more decompositions exist.
