Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127218, here are decompositions:

11 + 127207 = 127218
29 + 127189 = 127218
61 + 127157 = 127218
79 + 127139 = 127218
137 + 127081 = 127218
139 + 127079 = 127218
167 + 127051 = 127218
181 + 127037 = 127218

Showing the first eight; more decompositions exist.
