Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517218, here are decompositions:

7 + 517211 = 517218
11 + 517207 = 517218
29 + 517189 = 517218
41 + 517177 = 517218
67 + 517151 = 517218
89 + 517129 = 517218
127 + 517091 = 517218
131 + 517087 = 517218

Showing the first eight; more decompositions exist.
