Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020540, here are decompositions:

11 + 1020529 = 1020540
23 + 1020517 = 1020540
83 + 1020457 = 1020540
89 + 1020451 = 1020540
109 + 1020431 = 1020540
127 + 1020413 = 1020540
139 + 1020401 = 1020540
151 + 1020389 = 1020540

Showing the first eight; more decompositions exist.
