Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709864, here are decompositions:

43 + 8709821 = 8709864
47 + 8709817 = 8709864
71 + 8709793 = 8709864
83 + 8709781 = 8709864
113 + 8709751 = 8709864
127 + 8709737 = 8709864
151 + 8709713 = 8709864
167 + 8709697 = 8709864

Showing the first eight; more decompositions exist.
