Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990518, here are decompositions:

7 + 990511 = 990518
31 + 990487 = 990518
157 + 990361 = 990518
211 + 990307 = 990518
229 + 990289 = 990518
241 + 990277 = 990518
307 + 990211 = 990518
337 + 990181 = 990518

Showing the first eight; more decompositions exist.
