Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641356, here are decompositions:

5 + 8641351 = 8641356
7 + 8641349 = 8641356
29 + 8641327 = 8641356
37 + 8641319 = 8641356
47 + 8641309 = 8641356
67 + 8641289 = 8641356
83 + 8641273 = 8641356
107 + 8641249 = 8641356

Showing the first eight; more decompositions exist.
