Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628434, here are decompositions:

13 + 8628421 = 8628434
163 + 8628271 = 8628434
277 + 8628157 = 8628434
313 + 8628121 = 8628434
337 + 8628097 = 8628434
457 + 8627977 = 8628434
487 + 8627947 = 8628434
523 + 8627911 = 8628434

Showing the first eight; more decompositions exist.
