Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644272, here are decompositions:

11 + 8644261 = 8644272
19 + 8644253 = 8644272
29 + 8644243 = 8644272
41 + 8644231 = 8644272
59 + 8644213 = 8644272
101 + 8644171 = 8644272
149 + 8644123 = 8644272
181 + 8644091 = 8644272

Showing the first eight; more decompositions exist.
