Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628470, here are decompositions:

7 + 8628463 = 8628470
199 + 8628271 = 8628470
283 + 8628187 = 8628470
313 + 8628157 = 8628470
349 + 8628121 = 8628470
373 + 8628097 = 8628470
421 + 8628049 = 8628470
439 + 8628031 = 8628470

Showing the first eight; more decompositions exist.
