Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528078, here are decompositions:

37 + 528041 = 528078
97 + 527981 = 528078
137 + 527941 = 528078
149 + 527929 = 528078
157 + 527921 = 528078
181 + 527897 = 528078
197 + 527881 = 528078
227 + 527851 = 528078

Showing the first eight; more decompositions exist.
