Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636904, here are decompositions:

5 + 8636899 = 8636904
11 + 8636893 = 8636904
47 + 8636857 = 8636904
103 + 8636801 = 8636904
113 + 8636791 = 8636904
163 + 8636741 = 8636904
167 + 8636737 = 8636904
191 + 8636713 = 8636904

Showing the first eight; more decompositions exist.
