Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628378, here are decompositions:

19 + 8628359 = 8628378
29 + 8628349 = 8628378
107 + 8628271 = 8628378
191 + 8628187 = 8628378
197 + 8628181 = 8628378
229 + 8628149 = 8628378
257 + 8628121 = 8628378
271 + 8628107 = 8628378

Showing the first eight; more decompositions exist.
