Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990452, here are decompositions:

103 + 990349 = 990452
139 + 990313 = 990452
163 + 990289 = 990452
193 + 990259 = 990452
241 + 990211 = 990452
271 + 990181 = 990452
283 + 990169 = 990452
409 + 990043 = 990452

Showing the first eight; more decompositions exist.
