Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020506, here are decompositions:

127 + 1020379 = 1020506
283 + 1020223 = 1020506
349 + 1020157 = 1020506
397 + 1020109 = 1020506
457 + 1020049 = 1020506
463 + 1020043 = 1020506
499 + 1020007 = 1020506
607 + 1019899 = 1020506

Showing the first eight; more decompositions exist.
