Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16872, here are decompositions:

29 + 16843 = 16872
41 + 16831 = 16872
43 + 16829 = 16872
61 + 16811 = 16872
109 + 16763 = 16872
113 + 16759 = 16872
131 + 16741 = 16872
173 + 16699 = 16872

Showing the first eight; more decompositions exist.
