Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644356, here are decompositions:

29 + 8644327 = 8644356
103 + 8644253 = 8644356
113 + 8644243 = 8644356
199 + 8644157 = 8644356
233 + 8644123 = 8644356
307 + 8644049 = 8644356
337 + 8644019 = 8644356
359 + 8643997 = 8644356

Showing the first eight; more decompositions exist.
