Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5818, here are decompositions:

5 + 5813 = 5818
11 + 5807 = 5818
17 + 5801 = 5818
101 + 5717 = 5818
107 + 5711 = 5818
149 + 5669 = 5818
167 + 5651 = 5818
179 + 5639 = 5818

Showing the first eight; more decompositions exist.
