Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644476, here are decompositions:

19 + 8644457 = 8644476
23 + 8644453 = 8644476
37 + 8644439 = 8644476
79 + 8644397 = 8644476
149 + 8644327 = 8644476
223 + 8644253 = 8644476
233 + 8644243 = 8644476
263 + 8644213 = 8644476

Showing the first eight; more decompositions exist.
