Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720704, here are decompositions:

11 + 8720693 = 8720704
17 + 8720687 = 8720704
23 + 8720681 = 8720704
107 + 8720597 = 8720704
173 + 8720531 = 8720704
191 + 8720513 = 8720704
227 + 8720477 = 8720704
233 + 8720471 = 8720704

Showing the first eight; more decompositions exist.
