Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52720, here are decompositions:

11 + 52709 = 52720
23 + 52697 = 52720
29 + 52691 = 52720
47 + 52673 = 52720
53 + 52667 = 52720
89 + 52631 = 52720
137 + 52583 = 52720
149 + 52571 = 52720

Showing the first eight; more decompositions exist.
