Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630312, here are decompositions:

43 + 8630269 = 8630312
73 + 8630239 = 8630312
139 + 8630173 = 8630312
193 + 8630119 = 8630312
199 + 8630113 = 8630312
241 + 8630071 = 8630312
283 + 8630029 = 8630312
331 + 8629981 = 8630312

Showing the first eight; more decompositions exist.
