Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505318, here are decompositions:

5 + 505313 = 505318
17 + 505301 = 505318
41 + 505277 = 505318
131 + 505187 = 505318
137 + 505181 = 505318
179 + 505139 = 505318
227 + 505091 = 505318
251 + 505067 = 505318

Showing the first eight; more decompositions exist.
