Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641308, here are decompositions:

7 + 8641301 = 8641308
19 + 8641289 = 8641308
59 + 8641249 = 8641308
61 + 8641247 = 8641308
97 + 8641211 = 8641308
211 + 8641097 = 8641308
229 + 8641079 = 8641308
331 + 8640977 = 8641308

Showing the first eight; more decompositions exist.
