Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528132, here are decompositions:

5 + 528127 = 528132
41 + 528091 = 528132
79 + 528053 = 528132
89 + 528043 = 528132
131 + 528001 = 528132
139 + 527993 = 528132
149 + 527983 = 528132
151 + 527981 = 528132

Showing the first eight; more decompositions exist.
