Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518112, here are decompositions:

11 + 518101 = 518112
13 + 518099 = 518112
29 + 518083 = 518112
53 + 518059 = 518112
113 + 517999 = 518112
131 + 517981 = 518112
163 + 517949 = 518112
181 + 517931 = 518112

Showing the first eight; more decompositions exist.
