Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520206, here are decompositions:

13 + 520193 = 520206
83 + 520123 = 520206
103 + 520103 = 520206
139 + 520067 = 520206
163 + 520043 = 520206
263 + 519943 = 520206
283 + 519923 = 520206
317 + 519889 = 520206

Showing the first eight; more decompositions exist.
