Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021506, here are decompositions:

19 + 1021487 = 1021506
23 + 1021483 = 1021506
43 + 1021463 = 1021506
89 + 1021417 = 1021506
103 + 1021403 = 1021506
137 + 1021369 = 1021506
139 + 1021367 = 1021506
173 + 1021333 = 1021506

Showing the first eight; more decompositions exist.
