Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645376, here are decompositions:

17 + 8645359 = 8645376
23 + 8645353 = 8645376
83 + 8645293 = 8645376
107 + 8645269 = 8645376
109 + 8645267 = 8645376
137 + 8645239 = 8645376
139 + 8645237 = 8645376
197 + 8645179 = 8645376

Showing the first eight; more decompositions exist.
