Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016660, here are decompositions:

19 + 1016641 = 1016660
61 + 1016599 = 1016660
79 + 1016581 = 1016660
163 + 1016497 = 1016660
241 + 1016419 = 1016660
397 + 1016263 = 1016660
433 + 1016227 = 1016660
439 + 1016221 = 1016660

Showing the first eight; more decompositions exist.
