Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641480, here are decompositions:

11 + 8641469 = 8641480
47 + 8641433 = 8641480
59 + 8641421 = 8641480
131 + 8641349 = 8641480
149 + 8641331 = 8641480
179 + 8641301 = 8641480
191 + 8641289 = 8641480
233 + 8641247 = 8641480

Showing the first eight; more decompositions exist.
