Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518198, here are decompositions:

7 + 518191 = 518198
19 + 518179 = 518198
61 + 518137 = 518198
67 + 518131 = 518198
97 + 518101 = 518198
139 + 518059 = 518198
151 + 518047 = 518198
181 + 518017 = 518198

Showing the first eight; more decompositions exist.
