Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528980, here are decompositions:

7 + 528973 = 528980
13 + 528967 = 528980
97 + 528883 = 528980
103 + 528877 = 528980
157 + 528823 = 528980
181 + 528799 = 528980
271 + 528709 = 528980
307 + 528673 = 528980

Showing the first eight; more decompositions exist.
