Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636436, here are decompositions:

13 + 8636423 = 8636436
47 + 8636389 = 8636436
59 + 8636377 = 8636436
89 + 8636347 = 8636436
167 + 8636269 = 8636436
173 + 8636263 = 8636436
197 + 8636239 = 8636436
199 + 8636237 = 8636436

Showing the first eight; more decompositions exist.
