Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643152, here are decompositions:

3 + 8643149 = 8643152
19 + 8643133 = 8643152
31 + 8643121 = 8643152
43 + 8643109 = 8643152
61 + 8643091 = 8643152
139 + 8643013 = 8643152
163 + 8642989 = 8643152
241 + 8642911 = 8643152

Showing the first eight; more decompositions exist.
