Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528584, here are decompositions:

73 + 528511 = 528584
97 + 528487 = 528584
151 + 528433 = 528584
181 + 528403 = 528584
193 + 528391 = 528584
211 + 528373 = 528584
271 + 528313 = 528584
337 + 528247 = 528584

Showing the first eight; more decompositions exist.
