Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655184, here are decompositions:

11 + 8655173 = 8655184
17 + 8655167 = 8655184
113 + 8655071 = 8655184
137 + 8655047 = 8655184
173 + 8655011 = 8655184
311 + 8654873 = 8655184
347 + 8654837 = 8655184
431 + 8654753 = 8655184

Showing the first eight; more decompositions exist.
