Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625458, here are decompositions:

7 + 8625451 = 8625458
109 + 8625349 = 8625458
157 + 8625301 = 8625458
211 + 8625247 = 8625458
229 + 8625229 = 8625458
271 + 8625187 = 8625458
337 + 8625121 = 8625458
367 + 8625091 = 8625458

Showing the first eight; more decompositions exist.
