Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9700, here are decompositions:

3 + 9697 = 9700
11 + 9689 = 9700
23 + 9677 = 9700
71 + 9629 = 9700
113 + 9587 = 9700
149 + 9551 = 9700
167 + 9533 = 9700
179 + 9521 = 9700

Showing the first eight; more decompositions exist.
