Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520170, here are decompositions:

19 + 520151 = 520170
41 + 520129 = 520170
47 + 520123 = 520170
59 + 520111 = 520170
67 + 520103 = 520170
97 + 520073 = 520170
103 + 520067 = 520170
107 + 520063 = 520170

Showing the first eight; more decompositions exist.
