Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985428, here are decompositions:

11 + 985417 = 985428
29 + 985399 = 985428
89 + 985339 = 985428
97 + 985331 = 985428
127 + 985301 = 985428
137 + 985291 = 985428
149 + 985279 = 985428
151 + 985277 = 985428

Showing the first eight; more decompositions exist.
