Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583934, here are decompositions:

13 + 31583921 = 31583934
23 + 31583911 = 31583934
37 + 31583897 = 31583934
71 + 31583863 = 31583934
97 + 31583837 = 31583934
103 + 31583831 = 31583934
131 + 31583803 = 31583934
157 + 31583777 = 31583934

Showing the first eight; more decompositions exist.
