Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528178, here are decompositions:

11 + 528167 = 528178
41 + 528137 = 528178
47 + 528131 = 528178
71 + 528107 = 528178
137 + 528041 = 528178
191 + 527987 = 528178
197 + 527981 = 528178
257 + 527921 = 528178

Showing the first eight; more decompositions exist.
