Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528154, here are decompositions:

17 + 528137 = 528154
23 + 528131 = 528154
47 + 528107 = 528154
101 + 528053 = 528154
113 + 528041 = 528154
167 + 527987 = 528154
173 + 527981 = 528154
233 + 527921 = 528154

Showing the first eight; more decompositions exist.
