Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020564, here are decompositions:

7 + 1020557 = 1020564
23 + 1020541 = 1020564
47 + 1020517 = 1020564
73 + 1020491 = 1020564
107 + 1020457 = 1020564
113 + 1020451 = 1020564
151 + 1020413 = 1020564
157 + 1020407 = 1020564

Showing the first eight; more decompositions exist.
