Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644484, here are decompositions:

7 + 8644477 = 8644484
31 + 8644453 = 8644484
157 + 8644327 = 8644484
223 + 8644261 = 8644484
241 + 8644243 = 8644484
271 + 8644213 = 8644484
313 + 8644171 = 8644484
337 + 8644147 = 8644484

Showing the first eight; more decompositions exist.
