Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505378, here are decompositions:

11 + 505367 = 505378
59 + 505319 = 505378
101 + 505277 = 505378
191 + 505187 = 505378
197 + 505181 = 505378
239 + 505139 = 505378
281 + 505097 = 505378
311 + 505067 = 505378

Showing the first eight; more decompositions exist.
