Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616180, here are decompositions:

7 + 8616173 = 8616180
11 + 8616169 = 8616180
29 + 8616151 = 8616180
31 + 8616149 = 8616180
109 + 8616071 = 8616180
137 + 8616043 = 8616180
151 + 8616029 = 8616180
191 + 8615989 = 8616180

Showing the first eight; more decompositions exist.
