Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019660, here are decompositions:

3 + 1019657 = 1019660
13 + 1019647 = 1019660
43 + 1019617 = 1019660
97 + 1019563 = 1019660
127 + 1019533 = 1019660
151 + 1019509 = 1019660
157 + 1019503 = 1019660
181 + 1019479 = 1019660

Showing the first eight; more decompositions exist.
