Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518116, here are decompositions:

3 + 518113 = 518116
17 + 518099 = 518116
59 + 518057 = 518116
149 + 517967 = 518116
167 + 517949 = 518116
197 + 517919 = 518116
239 + 517877 = 518116
293 + 517823 = 518116

Showing the first eight; more decompositions exist.
