Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628370, here are decompositions:

11 + 8628359 = 8628370
17 + 8628353 = 8628370
137 + 8628233 = 8628370
167 + 8628203 = 8628370
197 + 8628173 = 8628370
239 + 8628131 = 8628370
263 + 8628107 = 8628370
293 + 8628077 = 8628370

Showing the first eight; more decompositions exist.
