Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990456, here are decompositions:

59 + 990397 = 990456
67 + 990389 = 990456
73 + 990383 = 990456
79 + 990377 = 990456
97 + 990359 = 990456
107 + 990349 = 990456
127 + 990329 = 990456
149 + 990307 = 990456

Showing the first eight; more decompositions exist.
