Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528416, here are decompositions:

3 + 528413 = 528416
13 + 528403 = 528416
43 + 528373 = 528416
103 + 528313 = 528416
127 + 528289 = 528416
193 + 528223 = 528416
199 + 528217 = 528416
373 + 528043 = 528416

Showing the first eight; more decompositions exist.
