Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688144, here are decompositions:

11 + 8688133 = 8688144
43 + 8688101 = 8688144
61 + 8688083 = 8688144
67 + 8688077 = 8688144
131 + 8688013 = 8688144
151 + 8687993 = 8688144
163 + 8687981 = 8688144
181 + 8687963 = 8688144

Showing the first eight; more decompositions exist.
