Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628426, here are decompositions:

5 + 8628421 = 8628426
19 + 8628407 = 8628426
43 + 8628383 = 8628426
67 + 8628359 = 8628426
73 + 8628353 = 8628426
193 + 8628233 = 8628426
223 + 8628203 = 8628426
239 + 8628187 = 8628426

Showing the first eight; more decompositions exist.
