Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583722, here are decompositions:

29 + 31583693 = 31583722
59 + 31583663 = 31583722
89 + 31583633 = 31583722
101 + 31583621 = 31583722
173 + 31583549 = 31583722
563 + 31583159 = 31583722
641 + 31583081 = 31583722
761 + 31582961 = 31583722

Showing the first eight; more decompositions exist.
