Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655480, here are decompositions:

23 + 8655457 = 8655480
47 + 8655433 = 8655480
59 + 8655421 = 8655480
79 + 8655401 = 8655480
109 + 8655371 = 8655480
131 + 8655349 = 8655480
137 + 8655343 = 8655480
149 + 8655331 = 8655480

Showing the first eight; more decompositions exist.
