Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583064, here are decompositions:

13 + 31583051 = 31583064
17 + 31583047 = 31583064
31 + 31583033 = 31583064
41 + 31583023 = 31583064
83 + 31582981 = 31583064
103 + 31582961 = 31583064
113 + 31582951 = 31583064
127 + 31582937 = 31583064

Showing the first eight; more decompositions exist.
