Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625470, here are decompositions:

3 + 8625467 = 8625470
19 + 8625451 = 8625470
127 + 8625343 = 8625470
157 + 8625313 = 8625470
181 + 8625289 = 8625470
223 + 8625247 = 8625470
241 + 8625229 = 8625470
283 + 8625187 = 8625470

Showing the first eight; more decompositions exist.
