Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625398, here are decompositions:

97 + 8625301 = 8625398
109 + 8625289 = 8625398
151 + 8625247 = 8625398
211 + 8625187 = 8625398
277 + 8625121 = 8625398
307 + 8625091 = 8625398
577 + 8624821 = 8625398
1087 + 8624311 = 8625398

Showing the first eight; more decompositions exist.
