Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616140, here are decompositions:

97 + 8616043 = 8616140
103 + 8616037 = 8616140
151 + 8615989 = 8616140
157 + 8615983 = 8616140
199 + 8615941 = 8616140
223 + 8615917 = 8616140
307 + 8615833 = 8616140
331 + 8615809 = 8616140

Showing the first eight; more decompositions exist.
