Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528160, here are decompositions:

23 + 528137 = 528160
29 + 528131 = 528160
53 + 528107 = 528160
107 + 528053 = 528160
167 + 527993 = 528160
173 + 527987 = 528160
179 + 527981 = 528160
239 + 527921 = 528160

Showing the first eight; more decompositions exist.
