Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528190, here are decompositions:

23 + 528167 = 528190
53 + 528137 = 528190
59 + 528131 = 528190
83 + 528107 = 528190
137 + 528053 = 528190
149 + 528041 = 528190
197 + 527993 = 528190
269 + 527921 = 528190

Showing the first eight; more decompositions exist.
