Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628494, here are decompositions:

13 + 8628481 = 8628494
31 + 8628463 = 8628494
73 + 8628421 = 8628494
223 + 8628271 = 8628494
307 + 8628187 = 8628494
313 + 8628181 = 8628494
337 + 8628157 = 8628494
373 + 8628121 = 8628494

Showing the first eight; more decompositions exist.
