Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16782, here are decompositions:

19 + 16763 = 16782
23 + 16759 = 16782
41 + 16741 = 16782
53 + 16729 = 16782
79 + 16703 = 16782
83 + 16699 = 16782
89 + 16693 = 16782
109 + 16673 = 16782

Showing the first eight; more decompositions exist.
