Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672340, here are decompositions:

7 + 8672333 = 8672340
43 + 8672297 = 8672340
67 + 8672273 = 8672340
73 + 8672267 = 8672340
101 + 8672239 = 8672340
137 + 8672203 = 8672340
139 + 8672201 = 8672340
163 + 8672177 = 8672340

Showing the first eight; more decompositions exist.
