Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528172, here are decompositions:

5 + 528167 = 528172
41 + 528131 = 528172
131 + 528041 = 528172
179 + 527993 = 528172
191 + 527981 = 528172
251 + 527921 = 528172
263 + 527909 = 528172
353 + 527819 = 528172

Showing the first eight; more decompositions exist.
