Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528554, here are decompositions:

43 + 528511 = 528554
67 + 528487 = 528554
151 + 528403 = 528554
163 + 528391 = 528554
181 + 528373 = 528554
241 + 528313 = 528554
307 + 528247 = 528554
331 + 528223 = 528554

Showing the first eight; more decompositions exist.
