Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10810, here are decompositions:

11 + 10799 = 10810
29 + 10781 = 10810
71 + 10739 = 10810
101 + 10709 = 10810
179 + 10631 = 10810
197 + 10613 = 10810
251 + 10559 = 10810
281 + 10529 = 10810

Showing the first eight; more decompositions exist.
