Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158228, here are decompositions:

19 + 158209 = 158228
67 + 158161 = 158228
151 + 158077 = 158228
157 + 158071 = 158228
181 + 158047 = 158228
199 + 158029 = 158228
211 + 158017 = 158228
229 + 157999 = 158228

Showing the first eight; more decompositions exist.
