Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672290, here are decompositions:

17 + 8672273 = 8672290
23 + 8672267 = 8672290
83 + 8672207 = 8672290
89 + 8672201 = 8672290
113 + 8672177 = 8672290
173 + 8672117 = 8672290
191 + 8672099 = 8672290
227 + 8672063 = 8672290

Showing the first eight; more decompositions exist.
