Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641476, here are decompositions:

5 + 8641471 = 8641476
7 + 8641469 = 8641476
23 + 8641453 = 8641476
43 + 8641433 = 8641476
47 + 8641429 = 8641476
127 + 8641349 = 8641476
149 + 8641327 = 8641476
157 + 8641319 = 8641476

Showing the first eight; more decompositions exist.
