Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720760, here are decompositions:

31 + 8720729 = 8720760
47 + 8720713 = 8720760
53 + 8720707 = 8720760
67 + 8720693 = 8720760
71 + 8720689 = 8720760
73 + 8720687 = 8720760
79 + 8720681 = 8720760
89 + 8720671 = 8720760

Showing the first eight; more decompositions exist.
