Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020818, here are decompositions:

61 + 1020757 = 1020818
67 + 1020751 = 1020818
109 + 1020709 = 1020818
151 + 1020667 = 1020818
199 + 1020619 = 1020818
229 + 1020589 = 1020818
277 + 1020541 = 1020818
367 + 1020451 = 1020818

Showing the first eight; more decompositions exist.
