Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986838, here are decompositions:

19 + 986819 = 986838
37 + 986801 = 986838
59 + 986779 = 986838
71 + 986767 = 986838
79 + 986759 = 986838
89 + 986749 = 986838
101 + 986737 = 986838
109 + 986729 = 986838

Showing the first eight; more decompositions exist.
