Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653278, here are decompositions:

17 + 8653261 = 8653278
19 + 8653259 = 8653278
37 + 8653241 = 8653278
41 + 8653237 = 8653278
47 + 8653231 = 8653278
59 + 8653219 = 8653278
71 + 8653207 = 8653278
79 + 8653199 = 8653278

Showing the first eight; more decompositions exist.
