Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518264, here are decompositions:

3 + 518261 = 518264
31 + 518233 = 518264
73 + 518191 = 518264
127 + 518137 = 518264
151 + 518113 = 518264
163 + 518101 = 518264
181 + 518083 = 518264
283 + 517981 = 518264

Showing the first eight; more decompositions exist.
