Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528976, here are decompositions:

3 + 528973 = 528976
5 + 528971 = 528976
29 + 528947 = 528976
47 + 528929 = 528976
113 + 528863 = 528976
197 + 528779 = 528976
257 + 528719 = 528976
269 + 528707 = 528976

Showing the first eight; more decompositions exist.
