Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1065216, here are decompositions:

7 + 1065209 = 1065216
43 + 1065173 = 1065216
79 + 1065137 = 1065216
83 + 1065133 = 1065216
107 + 1065109 = 1065216
127 + 1065089 = 1065216
157 + 1065059 = 1065216
179 + 1065037 = 1065216

Showing the first eight; more decompositions exist.
