Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999650, here are decompositions:

19 + 999631 = 999650
37 + 999613 = 999650
97 + 999553 = 999650
109 + 999541 = 999650
151 + 999499 = 999650
199 + 999451 = 999650
433 + 999217 = 999650
601 + 999049 = 999650

Showing the first eight; more decompositions exist.
