Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636444, here are decompositions:

67 + 8636377 = 8636444
97 + 8636347 = 8636444
181 + 8636263 = 8636444
277 + 8636167 = 8636444
307 + 8636137 = 8636444
337 + 8636107 = 8636444
463 + 8635981 = 8636444
547 + 8635897 = 8636444

Showing the first eight; more decompositions exist.
