Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625340, here are decompositions:

23 + 8625317 = 8625340
29 + 8625311 = 8625340
107 + 8625233 = 8625340
137 + 8625203 = 8625340
149 + 8625191 = 8625340
167 + 8625173 = 8625340
257 + 8625083 = 8625340
263 + 8625077 = 8625340

Showing the first eight; more decompositions exist.
