Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040858, here are decompositions:

31 + 1040827 = 1040858
37 + 1040821 = 1040858
61 + 1040797 = 1040858
79 + 1040779 = 1040858
109 + 1040749 = 1040858
127 + 1040731 = 1040858
199 + 1040659 = 1040858
229 + 1040629 = 1040858

Showing the first eight; more decompositions exist.
