Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020512, here are decompositions:

61 + 1020451 = 1020512
151 + 1020361 = 1020512
211 + 1020301 = 1020512
349 + 1020163 = 1020512
433 + 1020079 = 1020512
463 + 1020049 = 1020512
499 + 1020013 = 1020512
541 + 1019971 = 1020512

Showing the first eight; more decompositions exist.
