Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644332, here are decompositions:

5 + 8644327 = 8644332
31 + 8644301 = 8644332
71 + 8644261 = 8644332
79 + 8644253 = 8644332
89 + 8644243 = 8644332
101 + 8644231 = 8644332
241 + 8644091 = 8644332
251 + 8644081 = 8644332

Showing the first eight; more decompositions exist.
