Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518302, here are decompositions:

3 + 518299 = 518302
11 + 518291 = 518302
41 + 518261 = 518302
53 + 518249 = 518302
131 + 518171 = 518302
149 + 518153 = 518302
173 + 518129 = 518302
179 + 518123 = 518302

Showing the first eight; more decompositions exist.
