Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625344, here are decompositions:

31 + 8625313 = 8625344
43 + 8625301 = 8625344
97 + 8625247 = 8625344
157 + 8625187 = 8625344
223 + 8625121 = 8625344
271 + 8625073 = 8625344
331 + 8625013 = 8625344
337 + 8625007 = 8625344

Showing the first eight; more decompositions exist.
