Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655554, here are decompositions:

97 + 8655457 = 8655554
151 + 8655403 = 8655554
211 + 8655343 = 8655554
223 + 8655331 = 8655554
241 + 8655313 = 8655554
337 + 8655217 = 8655554
547 + 8655007 = 8655554
613 + 8654941 = 8655554

Showing the first eight; more decompositions exist.
