Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719802, here are decompositions:

31 + 8719771 = 8719802
103 + 8719699 = 8719802
139 + 8719663 = 8719802
199 + 8719603 = 8719802
211 + 8719591 = 8719802
229 + 8719573 = 8719802
283 + 8719519 = 8719802
499 + 8719303 = 8719802

Showing the first eight; more decompositions exist.
