Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016228, here are decompositions:

7 + 1016221 = 1016228
139 + 1016089 = 1016228
331 + 1015897 = 1016228
337 + 1015891 = 1016228
601 + 1015627 = 1016228
727 + 1015501 = 1016228
757 + 1015471 = 1016228
769 + 1015459 = 1016228

Showing the first eight; more decompositions exist.
