Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040286, here are decompositions:

59 + 1040227 = 1040286
67 + 1040219 = 1040286
83 + 1040203 = 1040286
97 + 1040189 = 1040286
103 + 1040183 = 1040286
127 + 1040159 = 1040286
167 + 1040119 = 1040286
173 + 1040113 = 1040286

Showing the first eight; more decompositions exist.
