Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627390, here are decompositions:

19 + 8627371 = 8627390
61 + 8627329 = 8627390
139 + 8627251 = 8627390
199 + 8627191 = 8627390
223 + 8627167 = 8627390
229 + 8627161 = 8627390
241 + 8627149 = 8627390
271 + 8627119 = 8627390

Showing the first eight; more decompositions exist.
