Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720734, here are decompositions:

5 + 8720729 = 8720734
41 + 8720693 = 8720734
47 + 8720687 = 8720734
53 + 8720681 = 8720734
107 + 8720627 = 8720734
137 + 8720597 = 8720734
251 + 8720483 = 8720734
257 + 8720477 = 8720734

Showing the first eight; more decompositions exist.
