Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520290, here are decompositions:

11 + 520279 = 520290
97 + 520193 = 520290
139 + 520151 = 520290
167 + 520123 = 520290
179 + 520111 = 520290
223 + 520067 = 520290
227 + 520063 = 520290
269 + 520021 = 520290

Showing the first eight; more decompositions exist.
