Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616144, here are decompositions:

13 + 8616131 = 8616144
73 + 8616071 = 8616144
101 + 8616043 = 8616144
107 + 8616037 = 8616144
181 + 8615963 = 8616144
227 + 8615917 = 8616144
263 + 8615881 = 8616144
311 + 8615833 = 8616144

Showing the first eight; more decompositions exist.
