Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999818, here are decompositions:

97 + 999721 = 999818
151 + 999667 = 999818
277 + 999541 = 999818
367 + 999451 = 999818
487 + 999331 = 999818
601 + 999217 = 999818
619 + 999199 = 999818
727 + 999091 = 999818

Showing the first eight; more decompositions exist.
