Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655180, here are decompositions:

7 + 8655173 = 8655180
13 + 8655167 = 8655180
31 + 8655149 = 8655180
109 + 8655071 = 8655180
139 + 8655041 = 8655180
151 + 8655029 = 8655180
173 + 8655007 = 8655180
199 + 8654981 = 8655180

Showing the first eight; more decompositions exist.
