Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607864, here are decompositions:

43 + 8607821 = 8607864
61 + 8607803 = 8607864
127 + 8607737 = 8607864
131 + 8607733 = 8607864
151 + 8607713 = 8607864
191 + 8607673 = 8607864
197 + 8607667 = 8607864
211 + 8607653 = 8607864

Showing the first eight; more decompositions exist.
