Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168218, here are decompositions:

7 + 168211 = 168218
67 + 168151 = 168218
109 + 168109 = 168218
151 + 168067 = 168218
181 + 168037 = 168218
307 + 167911 = 168218
331 + 167887 = 168218
409 + 167809 = 168218

Showing the first eight; more decompositions exist.
