Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985802, here are decompositions:

3 + 985799 = 985802
19 + 985783 = 985802
43 + 985759 = 985802
61 + 985741 = 985802
73 + 985729 = 985802
79 + 985723 = 985802
163 + 985639 = 985802
271 + 985531 = 985802

Showing the first eight; more decompositions exist.
