Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985458, here are decompositions:

7 + 985451 = 985458
11 + 985447 = 985458
41 + 985417 = 985458
59 + 985399 = 985458
79 + 985379 = 985458
107 + 985351 = 985458
127 + 985331 = 985458
151 + 985307 = 985458

Showing the first eight; more decompositions exist.
