Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518318, here are decompositions:

7 + 518311 = 518318
19 + 518299 = 518318
79 + 518239 = 518318
109 + 518209 = 518318
127 + 518191 = 518318
139 + 518179 = 518318
181 + 518137 = 518318
271 + 518047 = 518318

Showing the first eight; more decompositions exist.
