Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126018, here are decompositions:

5 + 126013 = 126018
7 + 126011 = 126018
17 + 126001 = 126018
59 + 125959 = 126018
89 + 125929 = 126018
97 + 125921 = 126018
131 + 125887 = 126018
197 + 125821 = 126018

Showing the first eight; more decompositions exist.
