Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641876, here are decompositions:

3 + 8641873 = 8641876
59 + 8641817 = 8641876
167 + 8641709 = 8641876
179 + 8641697 = 8641876
233 + 8641643 = 8641876
263 + 8641613 = 8641876
359 + 8641517 = 8641876
443 + 8641433 = 8641876

Showing the first eight; more decompositions exist.
