Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634728, here are decompositions:

31 + 8634697 = 8634728
61 + 8634667 = 8634728
211 + 8634517 = 8634728
307 + 8634421 = 8634728
331 + 8634397 = 8634728
337 + 8634391 = 8634728
757 + 8633971 = 8634728
769 + 8633959 = 8634728

Showing the first eight; more decompositions exist.
