Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10720, here are decompositions:

11 + 10709 = 10720
29 + 10691 = 10720
53 + 10667 = 10720
89 + 10631 = 10720
107 + 10613 = 10720
113 + 10607 = 10720
131 + 10589 = 10720
191 + 10529 = 10720

Showing the first eight; more decompositions exist.
