Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528290, here are decompositions:

43 + 528247 = 528290
67 + 528223 = 528290
73 + 528217 = 528290
127 + 528163 = 528290
163 + 528127 = 528290
193 + 528097 = 528290
199 + 528091 = 528290
277 + 528013 = 528290

Showing the first eight; more decompositions exist.
