Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628380, here are decompositions:

3 + 8628377 = 8628380
31 + 8628349 = 8628380
109 + 8628271 = 8628380
193 + 8628187 = 8628380
199 + 8628181 = 8628380
223 + 8628157 = 8628380
283 + 8628097 = 8628380
331 + 8628049 = 8628380

Showing the first eight; more decompositions exist.
