Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528284, here are decompositions:

37 + 528247 = 528284
61 + 528223 = 528284
67 + 528217 = 528284
157 + 528127 = 528284
193 + 528091 = 528284
241 + 528043 = 528284
271 + 528013 = 528284
283 + 528001 = 528284

Showing the first eight; more decompositions exist.
