Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80218, here are decompositions:

11 + 80207 = 80218
41 + 80177 = 80218
71 + 80147 = 80218
107 + 80111 = 80218
167 + 80051 = 80218
179 + 80039 = 80218
197 + 80021 = 80218
239 + 79979 = 80218

Showing the first eight; more decompositions exist.
