Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126030, here are decompositions:

7 + 126023 = 126030
11 + 126019 = 126030
17 + 126013 = 126030
19 + 126011 = 126030
29 + 126001 = 126030
67 + 125963 = 126030
71 + 125959 = 126030
89 + 125941 = 126030

Showing the first eight; more decompositions exist.
