Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641204, here are decompositions:

17 + 8641187 = 8641204
71 + 8641133 = 8641204
107 + 8641097 = 8641204
197 + 8641007 = 8641204
227 + 8640977 = 8641204
293 + 8640911 = 8641204
317 + 8640887 = 8641204
443 + 8640761 = 8641204

Showing the first eight; more decompositions exist.
