Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720802, here are decompositions:

5 + 8720797 = 8720802
19 + 8720783 = 8720802
29 + 8720773 = 8720802
31 + 8720771 = 8720802
73 + 8720729 = 8720802
89 + 8720713 = 8720802
109 + 8720693 = 8720802
113 + 8720689 = 8720802

Showing the first eight; more decompositions exist.
