Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179228, here are decompositions:

19 + 179209 = 179228
61 + 179167 = 179228
67 + 179161 = 179228
109 + 179119 = 179228
139 + 179089 = 179228
199 + 179029 = 179228
241 + 178987 = 179228
277 + 178951 = 179228

Showing the first eight; more decompositions exist.
