Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040220, here are decompositions:

17 + 1040203 = 1040220
29 + 1040191 = 1040220
31 + 1040189 = 1040220
37 + 1040183 = 1040220
53 + 1040167 = 1040220
59 + 1040161 = 1040220
61 + 1040159 = 1040220
67 + 1040153 = 1040220

Showing the first eight; more decompositions exist.
