Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16826, here are decompositions:

3 + 16823 = 16826
67 + 16759 = 16826
79 + 16747 = 16826
97 + 16729 = 16826
127 + 16699 = 16826
193 + 16633 = 16826
223 + 16603 = 16826
307 + 16519 = 16826

Showing the first eight; more decompositions exist.
