Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16812, here are decompositions:

53 + 16759 = 16812
71 + 16741 = 16812
83 + 16729 = 16812
109 + 16703 = 16812
113 + 16699 = 16812
139 + 16673 = 16812
151 + 16661 = 16812
163 + 16649 = 16812

Showing the first eight; more decompositions exist.
