Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720884, here are decompositions:

47 + 8720837 = 8720884
101 + 8720783 = 8720884
113 + 8720771 = 8720884
191 + 8720693 = 8720884
197 + 8720687 = 8720884
257 + 8720627 = 8720884
353 + 8720531 = 8720884
401 + 8720483 = 8720884

Showing the first eight; more decompositions exist.
