Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636378, here are decompositions:

31 + 8636347 = 8636378
109 + 8636269 = 8636378
139 + 8636239 = 8636378
211 + 8636167 = 8636378
241 + 8636137 = 8636378
271 + 8636107 = 8636378
379 + 8635999 = 8636378
397 + 8635981 = 8636378

Showing the first eight; more decompositions exist.
