Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986818, here are decompositions:

5 + 986813 = 986818
17 + 986801 = 986818
59 + 986759 = 986818
89 + 986729 = 986818
101 + 986717 = 986818
251 + 986567 = 986818
311 + 986507 = 986818
347 + 986471 = 986818

Showing the first eight; more decompositions exist.
