Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528004, here are decompositions:

3 + 528001 = 528004
11 + 527993 = 528004
17 + 527987 = 528004
23 + 527981 = 528004
83 + 527921 = 528004
107 + 527897 = 528004
251 + 527753 = 528004
263 + 527741 = 528004

Showing the first eight; more decompositions exist.
