Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016890, here are decompositions:

11 + 1016879 = 1016890
41 + 1016849 = 1016890
47 + 1016843 = 1016890
101 + 1016789 = 1016890
107 + 1016783 = 1016890
113 + 1016777 = 1016890
227 + 1016663 = 1016890
269 + 1016621 = 1016890

Showing the first eight; more decompositions exist.
