Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643148, here are decompositions:

5 + 8643143 = 8643148
11 + 8643137 = 8643148
71 + 8643077 = 8643148
89 + 8643059 = 8643148
197 + 8642951 = 8643148
251 + 8642897 = 8643148
401 + 8642747 = 8643148
557 + 8642591 = 8643148

Showing the first eight; more decompositions exist.
