Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655560, here are decompositions:

103 + 8655457 = 8655560
127 + 8655433 = 8655560
139 + 8655421 = 8655560
157 + 8655403 = 8655560
211 + 8655349 = 8655560
229 + 8655331 = 8655560
349 + 8655211 = 8655560
457 + 8655103 = 8655560

Showing the first eight; more decompositions exist.
