Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038818, here are decompositions:

7 + 1038811 = 1038818
61 + 1038757 = 1038818
97 + 1038721 = 1038818
127 + 1038691 = 1038818
181 + 1038637 = 1038818
199 + 1038619 = 1038818
229 + 1038589 = 1038818
331 + 1038487 = 1038818

Showing the first eight; more decompositions exist.
