Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167518, here are decompositions:

47 + 167471 = 167518
89 + 167429 = 167518
137 + 167381 = 167518
179 + 167339 = 167518
251 + 167267 = 167518
257 + 167261 = 167518
269 + 167249 = 167518
359 + 167159 = 167518

Showing the first eight; more decompositions exist.
