Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019750, here are decompositions:

3 + 1019747 = 1019750
19 + 1019731 = 1019750
37 + 1019713 = 1019750
103 + 1019647 = 1019750
241 + 1019509 = 1019750
271 + 1019479 = 1019750
283 + 1019467 = 1019750
307 + 1019443 = 1019750

Showing the first eight; more decompositions exist.
