Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2720, here are decompositions:

7 + 2713 = 2720
13 + 2707 = 2720
31 + 2689 = 2720
37 + 2683 = 2720
43 + 2677 = 2720
61 + 2659 = 2720
73 + 2647 = 2720
103 + 2617 = 2720

Showing the first eight; more decompositions exist.
