Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020518, here are decompositions:

61 + 1020457 = 1020518
67 + 1020451 = 1020518
139 + 1020379 = 1020518
157 + 1020361 = 1020518
181 + 1020337 = 1020518
271 + 1020247 = 1020518
409 + 1020109 = 1020518
439 + 1020079 = 1020518

Showing the first eight; more decompositions exist.
