Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641576, here are decompositions:

5 + 8641571 = 8641576
29 + 8641547 = 8641576
59 + 8641517 = 8641576
107 + 8641469 = 8641576
227 + 8641349 = 8641576
257 + 8641319 = 8641576
389 + 8641187 = 8641576
443 + 8641133 = 8641576

Showing the first eight; more decompositions exist.
