Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32720, here are decompositions:

3 + 32717 = 32720
7 + 32713 = 32720
13 + 32707 = 32720
67 + 32653 = 32720
73 + 32647 = 32720
109 + 32611 = 32720
151 + 32569 = 32720
157 + 32563 = 32720

Showing the first eight; more decompositions exist.
