Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1065218, here are decompositions:

109 + 1065109 = 1065218
127 + 1065091 = 1065218
181 + 1065037 = 1065218
199 + 1065019 = 1065218
229 + 1064989 = 1065218
241 + 1064977 = 1065218
277 + 1064941 = 1065218
307 + 1064911 = 1065218

Showing the first eight; more decompositions exist.
