Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608428, here are decompositions:

5 + 8608423 = 8608428
29 + 8608399 = 8608428
71 + 8608357 = 8608428
107 + 8608321 = 8608428
137 + 8608291 = 8608428
167 + 8608261 = 8608428
181 + 8608247 = 8608428
197 + 8608231 = 8608428

Showing the first eight; more decompositions exist.
