Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990422, here are decompositions:

61 + 990361 = 990422
73 + 990349 = 990422
109 + 990313 = 990422
163 + 990259 = 990422
211 + 990211 = 990422
241 + 990181 = 990422
271 + 990151 = 990422
379 + 990043 = 990422

Showing the first eight; more decompositions exist.
