Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528644, here are decompositions:

13 + 528631 = 528644
157 + 528487 = 528644
211 + 528433 = 528644
241 + 528403 = 528644
271 + 528373 = 528644
331 + 528313 = 528644
397 + 528247 = 528644
421 + 528223 = 528644

Showing the first eight; more decompositions exist.
