Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019666, here are decompositions:

3 + 1019663 = 1019666
19 + 1019647 = 1019666
103 + 1019563 = 1019666
157 + 1019509 = 1019666
163 + 1019503 = 1019666
199 + 1019467 = 1019666
223 + 1019443 = 1019666
313 + 1019353 = 1019666

Showing the first eight; more decompositions exist.
