Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528818, here are decompositions:

7 + 528811 = 528818
19 + 528799 = 528818
109 + 528709 = 528818
127 + 528691 = 528818
139 + 528679 = 528818
151 + 528667 = 528818
307 + 528511 = 528818
331 + 528487 = 528818

Showing the first eight; more decompositions exist.
