Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5820, here are decompositions:

7 + 5813 = 5820
13 + 5807 = 5820
19 + 5801 = 5820
29 + 5791 = 5820
37 + 5783 = 5820
41 + 5779 = 5820
71 + 5749 = 5820
79 + 5741 = 5820

Showing the first eight; more decompositions exist.
