Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985550, here are decompositions:

3 + 985547 = 985550
19 + 985531 = 985550
31 + 985519 = 985550
67 + 985483 = 985550
79 + 985471 = 985550
103 + 985447 = 985550
151 + 985399 = 985550
199 + 985351 = 985550

Showing the first eight; more decompositions exist.
