Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655450, here are decompositions:

17 + 8655433 = 8655450
29 + 8655421 = 8655450
47 + 8655403 = 8655450
79 + 8655371 = 8655450
101 + 8655349 = 8655450
107 + 8655343 = 8655450
137 + 8655313 = 8655450
163 + 8655287 = 8655450

Showing the first eight; more decompositions exist.
