Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583882, here are decompositions:

19 + 31583863 = 31583882
73 + 31583809 = 31583882
79 + 31583803 = 31583882
103 + 31583779 = 31583882
181 + 31583701 = 31583882
223 + 31583659 = 31583882
241 + 31583641 = 31583882
373 + 31583509 = 31583882

Showing the first eight; more decompositions exist.
