Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520230, here are decompositions:

17 + 520213 = 520230
37 + 520193 = 520230
79 + 520151 = 520230
101 + 520129 = 520230
107 + 520123 = 520230
127 + 520103 = 520230
157 + 520073 = 520230
163 + 520067 = 520230

Showing the first eight; more decompositions exist.
