Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636912, here are decompositions:

3 + 8636909 = 8636912
13 + 8636899 = 8636912
19 + 8636893 = 8636912
43 + 8636869 = 8636912
73 + 8636839 = 8636912
199 + 8636713 = 8636912
211 + 8636701 = 8636912
223 + 8636689 = 8636912

Showing the first eight; more decompositions exist.
