Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520266, here are decompositions:

53 + 520213 = 520266
73 + 520193 = 520266
137 + 520129 = 520266
163 + 520103 = 520266
193 + 520073 = 520266
199 + 520067 = 520266
223 + 520043 = 520266
269 + 519997 = 520266

Showing the first eight; more decompositions exist.
