Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5018, here are decompositions:

7 + 5011 = 5018
19 + 4999 = 5018
31 + 4987 = 5018
61 + 4957 = 5018
67 + 4951 = 5018
109 + 4909 = 5018
157 + 4861 = 5018
229 + 4789 = 5018

Showing the first eight; more decompositions exist.
