Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721676, here are decompositions:

3 + 8721673 = 8721676
59 + 8721617 = 8721676
137 + 8721539 = 8721676
233 + 8721443 = 8721676
263 + 8721413 = 8721676
317 + 8721359 = 8721676
347 + 8721329 = 8721676
479 + 8721197 = 8721676

Showing the first eight; more decompositions exist.
