Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5118, here are decompositions:

5 + 5113 = 5118
11 + 5107 = 5118
17 + 5101 = 5118
19 + 5099 = 5118
31 + 5087 = 5118
37 + 5081 = 5118
41 + 5077 = 5118
59 + 5059 = 5118

Showing the first eight; more decompositions exist.
