Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520278, here are decompositions:

37 + 520241 = 520278
127 + 520151 = 520278
149 + 520129 = 520278
167 + 520111 = 520278
211 + 520067 = 520278
257 + 520021 = 520278
281 + 519997 = 520278
307 + 519971 = 520278

Showing the first eight; more decompositions exist.
