Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21716, here are decompositions:

3 + 21713 = 21716
43 + 21673 = 21716
67 + 21649 = 21716
103 + 21613 = 21716
127 + 21589 = 21716
139 + 21577 = 21716
157 + 21559 = 21716
193 + 21523 = 21716

Showing the first eight; more decompositions exist.
