Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659120, here are decompositions:

23 + 8659097 = 8659120
53 + 8659067 = 8659120
59 + 8659061 = 8659120
83 + 8659037 = 8659120
101 + 8659019 = 8659120
131 + 8658989 = 8659120
137 + 8658983 = 8659120
179 + 8658941 = 8659120

Showing the first eight; more decompositions exist.
