Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990366, here are decompositions:

5 + 990361 = 990366
7 + 990359 = 990366
17 + 990349 = 990366
37 + 990329 = 990366
43 + 990323 = 990366
53 + 990313 = 990366
59 + 990307 = 990366
73 + 990293 = 990366

Showing the first eight; more decompositions exist.
