Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019732, here are decompositions:

3 + 1019729 = 1019732
19 + 1019713 = 1019732
31 + 1019701 = 1019732
199 + 1019533 = 1019732
223 + 1019509 = 1019732
229 + 1019503 = 1019732
283 + 1019449 = 1019732
379 + 1019353 = 1019732

Showing the first eight; more decompositions exist.
