Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528030, here are decompositions:

17 + 528013 = 528030
29 + 528001 = 528030
37 + 527993 = 528030
43 + 527987 = 528030
47 + 527983 = 528030
89 + 527941 = 528030
101 + 527929 = 528030
109 + 527921 = 528030

Showing the first eight; more decompositions exist.
