Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16868, here are decompositions:

37 + 16831 = 16868
109 + 16759 = 16868
127 + 16741 = 16868
139 + 16729 = 16868
211 + 16657 = 16868
307 + 16561 = 16868
349 + 16519 = 16868
421 + 16447 = 16868

Showing the first eight; more decompositions exist.
