Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986428, here are decompositions:

11 + 986417 = 986428
17 + 986411 = 986428
59 + 986369 = 986428
89 + 986339 = 986428
239 + 986189 = 986428
251 + 986177 = 986428
281 + 986147 = 986428
431 + 985997 = 986428

Showing the first eight; more decompositions exist.
