Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721076, here are decompositions:

47 + 8721029 = 8721076
107 + 8720969 = 8721076
239 + 8720837 = 8721076
257 + 8720819 = 8721076
269 + 8720807 = 8721076
293 + 8720783 = 8721076
347 + 8720729 = 8721076
383 + 8720693 = 8721076

Showing the first eight; more decompositions exist.
