Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19700, here are decompositions:

3 + 19697 = 19700
13 + 19687 = 19700
19 + 19681 = 19700
97 + 19603 = 19700
103 + 19597 = 19700
157 + 19543 = 19700
193 + 19507 = 19700
199 + 19501 = 19700

Showing the first eight; more decompositions exist.
