Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520152, here are decompositions:

23 + 520129 = 520152
29 + 520123 = 520152
41 + 520111 = 520152
79 + 520073 = 520152
89 + 520063 = 520152
109 + 520043 = 520152
131 + 520021 = 520152
163 + 519989 = 520152

Showing the first eight; more decompositions exist.
