Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29218, here are decompositions:

11 + 29207 = 29218
17 + 29201 = 29218
71 + 29147 = 29218
89 + 29129 = 29218
191 + 29027 = 29218
197 + 29021 = 29218
239 + 28979 = 29218
257 + 28961 = 29218

Showing the first eight; more decompositions exist.
