Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5720, here are decompositions:

3 + 5717 = 5720
19 + 5701 = 5720
31 + 5689 = 5720
37 + 5683 = 5720
61 + 5659 = 5720
67 + 5653 = 5720
73 + 5647 = 5720
79 + 5641 = 5720

Showing the first eight; more decompositions exist.
