Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528970, here are decompositions:

3 + 528967 = 528970
23 + 528947 = 528970
41 + 528929 = 528970
59 + 528911 = 528970
89 + 528881 = 528970
107 + 528863 = 528970
137 + 528833 = 528970
149 + 528821 = 528970

Showing the first eight; more decompositions exist.
