Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628368, here are decompositions:

19 + 8628349 = 8628368
97 + 8628271 = 8628368
181 + 8628187 = 8628368
211 + 8628157 = 8628368
271 + 8628097 = 8628368
337 + 8628031 = 8628368
349 + 8628019 = 8628368
421 + 8627947 = 8628368

Showing the first eight; more decompositions exist.
