Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636144, here are decompositions:

3 + 8636141 = 8636144
7 + 8636137 = 8636144
37 + 8636107 = 8636144
61 + 8636083 = 8636144
163 + 8635981 = 8636144
193 + 8635951 = 8636144
211 + 8635933 = 8636144
277 + 8635867 = 8636144

Showing the first eight; more decompositions exist.
