Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641288, here are decompositions:

41 + 8641247 = 8641288
101 + 8641187 = 8641288
191 + 8641097 = 8641288
281 + 8641007 = 8641288
311 + 8640977 = 8641288
401 + 8640887 = 8641288
521 + 8640767 = 8641288
569 + 8640719 = 8641288

Showing the first eight; more decompositions exist.
