Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672238, here are decompositions:

31 + 8672207 = 8672238
37 + 8672201 = 8672238
61 + 8672177 = 8672238
137 + 8672101 = 8672238
139 + 8672099 = 8672238
151 + 8672087 = 8672238
191 + 8672047 = 8672238
251 + 8671987 = 8672238

Showing the first eight; more decompositions exist.
