Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721376, here are decompositions:

5 + 8721371 = 8721376
17 + 8721359 = 8721376
47 + 8721329 = 8721376
107 + 8721269 = 8721376
137 + 8721239 = 8721376
179 + 8721197 = 8721376
347 + 8721029 = 8721376
557 + 8720819 = 8721376

Showing the first eight; more decompositions exist.
