Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520308, here are decompositions:

11 + 520297 = 520308
17 + 520291 = 520308
29 + 520279 = 520308
67 + 520241 = 520308
157 + 520151 = 520308
179 + 520129 = 520308
197 + 520111 = 520308
241 + 520067 = 520308

Showing the first eight; more decompositions exist.
