Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5180, here are decompositions:

13 + 5167 = 5180
61 + 5119 = 5180
67 + 5113 = 5180
73 + 5107 = 5180
79 + 5101 = 5180
103 + 5077 = 5180
157 + 5023 = 5180
181 + 4999 = 5180

Showing the first eight; more decompositions exist.
