Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625238, here are decompositions:

5 + 8625233 = 8625238
47 + 8625191 = 8625238
107 + 8625131 = 8625238
179 + 8625059 = 8625238
227 + 8625011 = 8625238
239 + 8624999 = 8625238
257 + 8624981 = 8625238
317 + 8624921 = 8625238

Showing the first eight; more decompositions exist.
