Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628270, here are decompositions:

37 + 8628233 = 8628270
67 + 8628203 = 8628270
83 + 8628187 = 8628270
89 + 8628181 = 8628270
97 + 8628173 = 8628270
109 + 8628161 = 8628270
113 + 8628157 = 8628270
139 + 8628131 = 8628270

Showing the first eight; more decompositions exist.
