Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017818, here are decompositions:

19 + 1017799 = 1017818
31 + 1017787 = 1017818
37 + 1017781 = 1017818
97 + 1017721 = 1017818
211 + 1017607 = 1017818
337 + 1017481 = 1017818
379 + 1017439 = 1017818
457 + 1017361 = 1017818

Showing the first eight; more decompositions exist.
