Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641482, here are decompositions:

11 + 8641471 = 8641482
13 + 8641469 = 8641482
29 + 8641453 = 8641482
53 + 8641429 = 8641482
61 + 8641421 = 8641482
131 + 8641351 = 8641482
151 + 8641331 = 8641482
163 + 8641319 = 8641482

Showing the first eight; more decompositions exist.
