Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518178, here are decompositions:

7 + 518171 = 518178
19 + 518159 = 518178
41 + 518137 = 518178
47 + 518131 = 518178
79 + 518099 = 518178
131 + 518047 = 518178
179 + 517999 = 518178
197 + 517981 = 518178

Showing the first eight; more decompositions exist.
