Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616210, here are decompositions:

7 + 8616203 = 8616210
11 + 8616199 = 8616210
13 + 8616197 = 8616210
23 + 8616187 = 8616210
37 + 8616173 = 8616210
41 + 8616169 = 8616210
59 + 8616151 = 8616210
61 + 8616149 = 8616210

Showing the first eight; more decompositions exist.
