Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040828, here are decompositions:

7 + 1040821 = 1040828
31 + 1040797 = 1040828
79 + 1040749 = 1040828
97 + 1040731 = 1040828
157 + 1040671 = 1040828
199 + 1040629 = 1040828
307 + 1040521 = 1040828
379 + 1040449 = 1040828

Showing the first eight; more decompositions exist.
