Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520146, here are decompositions:

17 + 520129 = 520146
23 + 520123 = 520146
43 + 520103 = 520146
73 + 520073 = 520146
79 + 520067 = 520146
83 + 520063 = 520146
103 + 520043 = 520146
127 + 520019 = 520146

Showing the first eight; more decompositions exist.
