Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990436, here are decompositions:

47 + 990389 = 990436
53 + 990383 = 990436
59 + 990377 = 990436
107 + 990329 = 990436
113 + 990323 = 990436
149 + 990287 = 990436
197 + 990239 = 990436
257 + 990179 = 990436

Showing the first eight; more decompositions exist.
