Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616312, here are decompositions:

13 + 8616299 = 8616312
31 + 8616281 = 8616312
41 + 8616271 = 8616312
71 + 8616241 = 8616312
109 + 8616203 = 8616312
113 + 8616199 = 8616312
139 + 8616173 = 8616312
163 + 8616149 = 8616312

Showing the first eight; more decompositions exist.
