Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641326, here are decompositions:

7 + 8641319 = 8641326
17 + 8641309 = 8641326
37 + 8641289 = 8641326
53 + 8641273 = 8641326
79 + 8641247 = 8641326
139 + 8641187 = 8641326
179 + 8641147 = 8641326
193 + 8641133 = 8641326

Showing the first eight; more decompositions exist.
