Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528100, here are decompositions:

3 + 528097 = 528100
47 + 528053 = 528100
59 + 528041 = 528100
107 + 527993 = 528100
113 + 527987 = 528100
179 + 527921 = 528100
191 + 527909 = 528100
257 + 527843 = 528100

Showing the first eight; more decompositions exist.
