Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655160, here are decompositions:

11 + 8655149 = 8655160
89 + 8655071 = 8655160
113 + 8655047 = 8655160
131 + 8655029 = 8655160
149 + 8655011 = 8655160
179 + 8654981 = 8655160
263 + 8654897 = 8655160
389 + 8654771 = 8655160

Showing the first eight; more decompositions exist.
