Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637152, here are decompositions:

19 + 8637133 = 8637152
61 + 8637091 = 8637152
163 + 8636989 = 8637152
193 + 8636959 = 8637152
229 + 8636923 = 8637152
241 + 8636911 = 8637152
283 + 8636869 = 8637152
313 + 8636839 = 8637152

Showing the first eight; more decompositions exist.
