Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020386, here are decompositions:

7 + 1020379 = 1020386
127 + 1020259 = 1020386
139 + 1020247 = 1020386
163 + 1020223 = 1020386
223 + 1020163 = 1020386
229 + 1020157 = 1020386
277 + 1020109 = 1020386
307 + 1020079 = 1020386

Showing the first eight; more decompositions exist.
