Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118218, here are decompositions:

5 + 118213 = 118218
7 + 118211 = 118218
29 + 118189 = 118218
47 + 118171 = 118218
71 + 118147 = 118218
137 + 118081 = 118218
157 + 118061 = 118218
167 + 118051 = 118218

Showing the first eight; more decompositions exist.
