Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5808, here are decompositions:

7 + 5801 = 5808
17 + 5791 = 5808
29 + 5779 = 5808
59 + 5749 = 5808
67 + 5741 = 5808
71 + 5737 = 5808
97 + 5711 = 5808
107 + 5701 = 5808

Showing the first eight; more decompositions exist.
