Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986786, here are decompositions:

7 + 986779 = 986786
19 + 986767 = 986786
37 + 986749 = 986786
67 + 986719 = 986786
79 + 986707 = 986786
127 + 986659 = 986786
193 + 986593 = 986786
223 + 986563 = 986786

Showing the first eight; more decompositions exist.
