Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180228, here are decompositions:

7 + 180221 = 180228
17 + 180211 = 180228
47 + 180181 = 180228
67 + 180161 = 180228
131 + 180097 = 180228
151 + 180077 = 180228
157 + 180071 = 180228
227 + 180001 = 180228

Showing the first eight; more decompositions exist.
