Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625392, here are decompositions:

43 + 8625349 = 8625392
79 + 8625313 = 8625392
103 + 8625289 = 8625392
163 + 8625229 = 8625392
271 + 8625121 = 8625392
379 + 8625013 = 8625392
439 + 8624953 = 8625392
463 + 8624929 = 8625392

Showing the first eight; more decompositions exist.
