Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528112, here are decompositions:

5 + 528107 = 528112
59 + 528053 = 528112
71 + 528041 = 528112
131 + 527981 = 528112
191 + 527921 = 528112
269 + 527843 = 528112
293 + 527819 = 528112
359 + 527753 = 528112

Showing the first eight; more decompositions exist.
