Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518106, here are decompositions:

5 + 518101 = 518106
7 + 518099 = 518106
23 + 518083 = 518106
47 + 518059 = 518106
59 + 518047 = 518106
89 + 518017 = 518106
107 + 517999 = 518106
139 + 517967 = 518106

Showing the first eight; more decompositions exist.
