Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152218, here are decompositions:

5 + 152213 = 152218
29 + 152189 = 152218
71 + 152147 = 152218
107 + 152111 = 152218
137 + 152081 = 152218
179 + 152039 = 152218
191 + 152027 = 152218
251 + 151967 = 152218

Showing the first eight; more decompositions exist.
