Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528150, here are decompositions:

13 + 528137 = 528150
19 + 528131 = 528150
23 + 528127 = 528150
43 + 528107 = 528150
53 + 528097 = 528150
59 + 528091 = 528150
97 + 528053 = 528150
107 + 528043 = 528150

Showing the first eight; more decompositions exist.
