Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720716, here are decompositions:

3 + 8720713 = 8720716
23 + 8720693 = 8720716
29 + 8720687 = 8720716
89 + 8720627 = 8720716
227 + 8720489 = 8720716
233 + 8720483 = 8720716
239 + 8720477 = 8720716
269 + 8720447 = 8720716

Showing the first eight; more decompositions exist.
