Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505342, here are decompositions:

3 + 505339 = 505342
23 + 505319 = 505342
29 + 505313 = 505342
41 + 505301 = 505342
59 + 505283 = 505342
251 + 505091 = 505342
269 + 505073 = 505342
281 + 505061 = 505342

Showing the first eight; more decompositions exist.
