Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19708, here are decompositions:

11 + 19697 = 19708
47 + 19661 = 19708
131 + 19577 = 19708
137 + 19571 = 19708
149 + 19559 = 19708
167 + 19541 = 19708
239 + 19469 = 19708
251 + 19457 = 19708

Showing the first eight; more decompositions exist.
