Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189228, here are decompositions:

5 + 189223 = 189228
29 + 189199 = 189228
41 + 189187 = 189228
59 + 189169 = 189228
79 + 189149 = 189228
89 + 189139 = 189228
101 + 189127 = 189228
167 + 189061 = 189228

Showing the first eight; more decompositions exist.
