Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649210, here are decompositions:

13 + 8649197 = 8649210
19 + 8649191 = 8649210
23 + 8649187 = 8649210
107 + 8649103 = 8649210
131 + 8649079 = 8649210
139 + 8649071 = 8649210
149 + 8649061 = 8649210
181 + 8649029 = 8649210

Showing the first eight; more decompositions exist.
