Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583962, here are decompositions:

41 + 31583921 = 31583962
131 + 31583831 = 31583962
191 + 31583771 = 31583962
233 + 31583729 = 31583962
269 + 31583693 = 31583962
401 + 31583561 = 31583962
881 + 31583081 = 31583962
911 + 31583051 = 31583962

Showing the first eight; more decompositions exist.
