Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005864, here are decompositions:

31 + 1005833 = 1005864
37 + 1005827 = 1005864
43 + 1005821 = 1005864
103 + 1005761 = 1005864
113 + 1005751 = 1005864
163 + 1005701 = 1005864
227 + 1005637 = 1005864
271 + 1005593 = 1005864

Showing the first eight; more decompositions exist.
