Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641472, here are decompositions:

3 + 8641469 = 8641472
19 + 8641453 = 8641472
43 + 8641429 = 8641472
163 + 8641309 = 8641472
199 + 8641273 = 8641472
223 + 8641249 = 8641472
241 + 8641231 = 8641472
379 + 8641093 = 8641472

Showing the first eight; more decompositions exist.
