Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990494, here are decompositions:

7 + 990487 = 990494
31 + 990463 = 990494
97 + 990397 = 990494
163 + 990331 = 990494
181 + 990313 = 990494
283 + 990211 = 990494
313 + 990181 = 990494
331 + 990163 = 990494

Showing the first eight; more decompositions exist.
