Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528028, here are decompositions:

41 + 527987 = 528028
47 + 527981 = 528028
107 + 527921 = 528028
131 + 527897 = 528028
239 + 527789 = 528028
401 + 527627 = 528028
521 + 527507 = 528028
587 + 527441 = 528028

Showing the first eight; more decompositions exist.
