Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990470, here are decompositions:

7 + 990463 = 990470
73 + 990397 = 990470
109 + 990361 = 990470
139 + 990331 = 990470
157 + 990313 = 990470
163 + 990307 = 990470
181 + 990289 = 990470
193 + 990277 = 990470

Showing the first eight; more decompositions exist.
