Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528972, here are decompositions:

5 + 528967 = 528972
43 + 528929 = 528972
61 + 528911 = 528972
89 + 528883 = 528972
109 + 528863 = 528972
139 + 528833 = 528972
149 + 528823 = 528972
151 + 528821 = 528972

Showing the first eight; more decompositions exist.
