Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634388, here are decompositions:

5 + 8634383 = 8634388
17 + 8634371 = 8634388
29 + 8634359 = 8634388
41 + 8634347 = 8634388
89 + 8634299 = 8634388
137 + 8634251 = 8634388
227 + 8634161 = 8634388
251 + 8634137 = 8634388

Showing the first eight; more decompositions exist.
