Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608388, here are decompositions:

31 + 8608357 = 8608388
67 + 8608321 = 8608388
97 + 8608291 = 8608388
127 + 8608261 = 8608388
157 + 8608231 = 8608388
241 + 8608147 = 8608388
307 + 8608081 = 8608388
379 + 8608009 = 8608388

Showing the first eight; more decompositions exist.
