Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634440, here are decompositions:

13 + 8634427 = 8634440
19 + 8634421 = 8634440
43 + 8634397 = 8634440
181 + 8634259 = 8634440
229 + 8634211 = 8634440
271 + 8634169 = 8634440
277 + 8634163 = 8634440
307 + 8634133 = 8634440

Showing the first eight; more decompositions exist.
