Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016880, here are decompositions:

31 + 1016849 = 1016880
37 + 1016843 = 1016880
41 + 1016839 = 1016880
97 + 1016783 = 1016880
103 + 1016777 = 1016880
107 + 1016773 = 1016880
131 + 1016749 = 1016880
149 + 1016731 = 1016880

Showing the first eight; more decompositions exist.
