Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19710, here are decompositions:

11 + 19699 = 19710
13 + 19697 = 19710
23 + 19687 = 19710
29 + 19681 = 19710
101 + 19609 = 19710
107 + 19603 = 19710
113 + 19597 = 19710
127 + 19583 = 19710

Showing the first eight; more decompositions exist.
