Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020528, here are decompositions:

11 + 1020517 = 1020528
37 + 1020491 = 1020528
71 + 1020457 = 1020528
97 + 1020431 = 1020528
109 + 1020419 = 1020528
127 + 1020401 = 1020528
139 + 1020389 = 1020528
149 + 1020379 = 1020528

Showing the first eight; more decompositions exist.
