Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628338, here are decompositions:

67 + 8628271 = 8628338
151 + 8628187 = 8628338
157 + 8628181 = 8628338
181 + 8628157 = 8628338
241 + 8628097 = 8628338
307 + 8628031 = 8628338
331 + 8628007 = 8628338
487 + 8627851 = 8628338

Showing the first eight; more decompositions exist.
