Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636906, here are decompositions:

7 + 8636899 = 8636906
13 + 8636893 = 8636906
37 + 8636869 = 8636906
67 + 8636839 = 8636906
127 + 8636779 = 8636906
193 + 8636713 = 8636906
307 + 8636599 = 8636906
367 + 8636539 = 8636906

Showing the first eight; more decompositions exist.
