Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020560, here are decompositions:

3 + 1020557 = 1020560
19 + 1020541 = 1020560
31 + 1020529 = 1020560
43 + 1020517 = 1020560
103 + 1020457 = 1020560
109 + 1020451 = 1020560
181 + 1020379 = 1020560
199 + 1020361 = 1020560

Showing the first eight; more decompositions exist.
