Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672328, here are decompositions:

31 + 8672297 = 8672328
61 + 8672267 = 8672328
89 + 8672239 = 8672328
127 + 8672201 = 8672328
151 + 8672177 = 8672328
167 + 8672161 = 8672328
211 + 8672117 = 8672328
227 + 8672101 = 8672328

Showing the first eight; more decompositions exist.
