Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020266, here are decompositions:

7 + 1020259 = 1020266
19 + 1020247 = 1020266
43 + 1020223 = 1020266
103 + 1020163 = 1020266
109 + 1020157 = 1020266
157 + 1020109 = 1020266
223 + 1020043 = 1020266
229 + 1020037 = 1020266

Showing the first eight; more decompositions exist.
