Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019966, here are decompositions:

67 + 1019899 = 1019966
109 + 1019857 = 1019966
127 + 1019839 = 1019966
139 + 1019827 = 1019966
349 + 1019617 = 1019966
433 + 1019533 = 1019966
457 + 1019509 = 1019966
463 + 1019503 = 1019966

Showing the first eight; more decompositions exist.
