Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168532, here are decompositions:

5 + 168527 = 168532
41 + 168491 = 168532
83 + 168449 = 168532
179 + 168353 = 168532
239 + 168293 = 168532
251 + 168281 = 168532
263 + 168269 = 168532
269 + 168263 = 168532

Showing the first eight; more decompositions exist.
