Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528988, here are decompositions:

17 + 528971 = 528988
41 + 528947 = 528988
59 + 528929 = 528988
107 + 528881 = 528988
167 + 528821 = 528988
197 + 528791 = 528988
269 + 528719 = 528988
281 + 528707 = 528988

Showing the first eight; more decompositions exist.
