Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990434, here are decompositions:

37 + 990397 = 990434
73 + 990361 = 990434
103 + 990331 = 990434
127 + 990307 = 990434
157 + 990277 = 990434
223 + 990211 = 990434
271 + 990163 = 990434
283 + 990151 = 990434

Showing the first eight; more decompositions exist.
