Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020680, here are decompositions:

13 + 1020667 = 1020680
61 + 1020619 = 1020680
97 + 1020583 = 1020680
139 + 1020541 = 1020680
151 + 1020529 = 1020680
163 + 1020517 = 1020680
223 + 1020457 = 1020680
229 + 1020451 = 1020680

Showing the first eight; more decompositions exist.
