Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634144, here are decompositions:

5 + 8634139 = 8634144
7 + 8634137 = 8634144
11 + 8634133 = 8634144
37 + 8634107 = 8634144
67 + 8634077 = 8634144
163 + 8633981 = 8634144
173 + 8633971 = 8634144
193 + 8633951 = 8634144

Showing the first eight; more decompositions exist.
