Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720832, here are decompositions:

13 + 8720819 = 8720832
23 + 8720809 = 8720832
59 + 8720773 = 8720832
61 + 8720771 = 8720832
103 + 8720729 = 8720832
139 + 8720693 = 8720832
151 + 8720681 = 8720832
251 + 8720581 = 8720832

Showing the first eight; more decompositions exist.
