Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 141228, here are decompositions:

5 + 141223 = 141228
7 + 141221 = 141228
19 + 141209 = 141228
29 + 141199 = 141228
47 + 141181 = 141228
67 + 141161 = 141228
71 + 141157 = 141228
97 + 141131 = 141228

Showing the first eight; more decompositions exist.
