Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990290, here are decompositions:

3 + 990287 = 990290
13 + 990277 = 990290
31 + 990259 = 990290
79 + 990211 = 990290
109 + 990181 = 990290
127 + 990163 = 990290
139 + 990151 = 990290
277 + 990013 = 990290

Showing the first eight; more decompositions exist.
