Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528504, here are decompositions:

13 + 528491 = 528504
17 + 528487 = 528504
71 + 528433 = 528504
101 + 528403 = 528504
103 + 528401 = 528504
113 + 528391 = 528504
131 + 528373 = 528504
191 + 528313 = 528504

Showing the first eight; more decompositions exist.
