Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720514, here are decompositions:

17 + 8720497 = 8720514
31 + 8720483 = 8720514
37 + 8720477 = 8720514
43 + 8720471 = 8720514
67 + 8720447 = 8720514
83 + 8720431 = 8720514
97 + 8720417 = 8720514
107 + 8720407 = 8720514

Showing the first eight; more decompositions exist.
