Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583924, here are decompositions:

3 + 31583921 = 31583924
13 + 31583911 = 31583924
61 + 31583863 = 31583924
67 + 31583857 = 31583924
223 + 31583701 = 31583924
283 + 31583641 = 31583924
397 + 31583527 = 31583924
487 + 31583437 = 31583924

Showing the first eight; more decompositions exist.
