Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985518, here are decompositions:

19 + 985499 = 985518
31 + 985487 = 985518
47 + 985471 = 985518
67 + 985451 = 985518
71 + 985447 = 985518
101 + 985417 = 985518
139 + 985379 = 985518
167 + 985351 = 985518

Showing the first eight; more decompositions exist.
