Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672188, here are decompositions:

11 + 8672177 = 8672188
71 + 8672117 = 8672188
89 + 8672099 = 8672188
101 + 8672087 = 8672188
197 + 8671991 = 8672188
251 + 8671937 = 8672188
269 + 8671919 = 8672188
281 + 8671907 = 8672188

Showing the first eight; more decompositions exist.
