Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985628, here are decompositions:

31 + 985597 = 985628
97 + 985531 = 985628
109 + 985519 = 985628
157 + 985471 = 985628
181 + 985447 = 985628
211 + 985417 = 985628
229 + 985399 = 985628
277 + 985351 = 985628

Showing the first eight; more decompositions exist.
