Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641276, here are decompositions:

3 + 8641273 = 8641276
29 + 8641247 = 8641276
89 + 8641187 = 8641276
179 + 8641097 = 8641276
197 + 8641079 = 8641276
269 + 8641007 = 8641276
389 + 8640887 = 8641276
509 + 8640767 = 8641276

Showing the first eight; more decompositions exist.
