Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616428, here are decompositions:

31 + 8616397 = 8616428
109 + 8616319 = 8616428
157 + 8616271 = 8616428
181 + 8616247 = 8616428
211 + 8616217 = 8616428
229 + 8616199 = 8616428
241 + 8616187 = 8616428
277 + 8616151 = 8616428

Showing the first eight; more decompositions exist.
