Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012220, here are decompositions:

3 + 1012217 = 1012220
7 + 1012213 = 1012220
19 + 1012201 = 1012220
31 + 1012189 = 1012220
37 + 1012183 = 1012220
61 + 1012159 = 1012220
73 + 1012147 = 1012220
127 + 1012093 = 1012220

Showing the first eight; more decompositions exist.
