Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518186, here are decompositions:

7 + 518179 = 518186
73 + 518113 = 518186
103 + 518083 = 518186
127 + 518059 = 518186
139 + 518047 = 518186
313 + 517873 = 518186
439 + 517747 = 518186
457 + 517729 = 518186

Showing the first eight; more decompositions exist.
