Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583966, here are decompositions:

103 + 31583863 = 31583966
109 + 31583857 = 31583966
157 + 31583809 = 31583966
163 + 31583803 = 31583966
307 + 31583659 = 31583966
439 + 31583527 = 31583966
457 + 31583509 = 31583966
613 + 31583353 = 31583966

Showing the first eight; more decompositions exist.
