Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655120, here are decompositions:

17 + 8655103 = 8655120
73 + 8655047 = 8655120
79 + 8655041 = 8655120
83 + 8655037 = 8655120
109 + 8655011 = 8655120
113 + 8655007 = 8655120
139 + 8654981 = 8655120
179 + 8654941 = 8655120

Showing the first eight; more decompositions exist.
