Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16878, here are decompositions:

7 + 16871 = 16878
47 + 16831 = 16878
67 + 16811 = 16878
131 + 16747 = 16878
137 + 16741 = 16878
149 + 16729 = 16878
179 + 16699 = 16878
227 + 16651 = 16878

Showing the first eight; more decompositions exist.
