Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16886, here are decompositions:

3 + 16883 = 16886
7 + 16879 = 16886
43 + 16843 = 16886
127 + 16759 = 16886
139 + 16747 = 16886
157 + 16729 = 16886
193 + 16693 = 16886
229 + 16657 = 16886

Showing the first eight; more decompositions exist.
