Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528018, here are decompositions:

5 + 528013 = 528018
17 + 528001 = 528018
31 + 527987 = 528018
37 + 527981 = 528018
89 + 527929 = 528018
97 + 527921 = 528018
109 + 527909 = 528018
137 + 527881 = 528018

Showing the first eight; more decompositions exist.
