Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636288, here are decompositions:

19 + 8636269 = 8636288
151 + 8636137 = 8636288
181 + 8636107 = 8636288
307 + 8635981 = 8636288
337 + 8635951 = 8636288
421 + 8635867 = 8636288
439 + 8635849 = 8636288
571 + 8635717 = 8636288

Showing the first eight; more decompositions exist.
