Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528244, here are decompositions:

47 + 528197 = 528244
53 + 528191 = 528244
107 + 528137 = 528244
113 + 528131 = 528244
137 + 528107 = 528244
191 + 528053 = 528244
251 + 527993 = 528244
257 + 527987 = 528244

Showing the first eight; more decompositions exist.
