Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512278, here are decompositions:

29 + 512249 = 512278
71 + 512207 = 512278
131 + 512147 = 512278
257 + 512021 = 512278
269 + 512009 = 512278
281 + 511997 = 512278
317 + 511961 = 512278
419 + 511859 = 512278

Showing the first eight; more decompositions exist.
