Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15018, here are decompositions:

5 + 15013 = 15018
61 + 14957 = 15018
67 + 14951 = 15018
71 + 14947 = 15018
79 + 14939 = 15018
89 + 14929 = 15018
127 + 14891 = 15018
131 + 14887 = 15018

Showing the first eight; more decompositions exist.
