Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701720, here are decompositions:

11 + 8701709 = 8701720
17 + 8701703 = 8701720
89 + 8701631 = 8701720
149 + 8701571 = 8701720
191 + 8701529 = 8701720
227 + 8701493 = 8701720
263 + 8701457 = 8701720
311 + 8701409 = 8701720

Showing the first eight; more decompositions exist.
