Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690470, here are decompositions:

17 + 8690453 = 8690470
59 + 8690411 = 8690470
71 + 8690399 = 8690470
83 + 8690387 = 8690470
137 + 8690333 = 8690470
167 + 8690303 = 8690470
179 + 8690291 = 8690470
293 + 8690177 = 8690470

Showing the first eight; more decompositions exist.
