Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986826, here are decompositions:

7 + 986819 = 986826
13 + 986813 = 986826
47 + 986779 = 986826
59 + 986767 = 986826
67 + 986759 = 986826
89 + 986737 = 986826
97 + 986729 = 986826
107 + 986719 = 986826

Showing the first eight; more decompositions exist.
