Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720706, here are decompositions:

13 + 8720693 = 8720706
17 + 8720689 = 8720706
19 + 8720687 = 8720706
79 + 8720627 = 8720706
83 + 8720623 = 8720706
89 + 8720617 = 8720706
109 + 8720597 = 8720706
149 + 8720557 = 8720706

Showing the first eight; more decompositions exist.
