Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721346, here are decompositions:

17 + 8721329 = 8721346
47 + 8721299 = 8721346
107 + 8721239 = 8721346
149 + 8721197 = 8721346
269 + 8721077 = 8721346
317 + 8721029 = 8721346
509 + 8720837 = 8721346
563 + 8720783 = 8721346

Showing the first eight; more decompositions exist.
