Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583984, here are decompositions:

13 + 31583971 = 31583984
43 + 31583941 = 31583984
73 + 31583911 = 31583984
127 + 31583857 = 31583984
181 + 31583803 = 31583984
283 + 31583701 = 31583984
457 + 31583527 = 31583984
463 + 31583521 = 31583984

Showing the first eight; more decompositions exist.
