Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990536, here are decompositions:

7 + 990529 = 990536
13 + 990523 = 990536
67 + 990469 = 990536
73 + 990463 = 990536
139 + 990397 = 990536
223 + 990313 = 990536
229 + 990307 = 990536
277 + 990259 = 990536

Showing the first eight; more decompositions exist.
