Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646210, here are decompositions:

29 + 8646181 = 8646210
47 + 8646163 = 8646210
103 + 8646107 = 8646210
107 + 8646103 = 8646210
149 + 8646061 = 8646210
151 + 8646059 = 8646210
193 + 8646017 = 8646210
229 + 8645981 = 8646210

Showing the first eight; more decompositions exist.
