Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528180, here are decompositions:

13 + 528167 = 528180
17 + 528163 = 528180
43 + 528137 = 528180
53 + 528127 = 528180
73 + 528107 = 528180
83 + 528097 = 528180
89 + 528091 = 528180
127 + 528053 = 528180

Showing the first eight; more decompositions exist.
