Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518108, here are decompositions:

7 + 518101 = 518108
61 + 518047 = 518108
109 + 517999 = 518108
127 + 517981 = 518108
181 + 517927 = 518108
277 + 517831 = 518108
379 + 517729 = 518108
397 + 517711 = 518108

Showing the first eight; more decompositions exist.
