Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528320, here are decompositions:

3 + 528317 = 528320
7 + 528313 = 528320
31 + 528289 = 528320
73 + 528247 = 528320
97 + 528223 = 528320
103 + 528217 = 528320
157 + 528163 = 528320
193 + 528127 = 528320

Showing the first eight; more decompositions exist.
