Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655590, here are decompositions:

157 + 8655433 = 8655590
241 + 8655349 = 8655590
277 + 8655313 = 8655590
283 + 8655307 = 8655590
331 + 8655259 = 8655590
373 + 8655217 = 8655590
379 + 8655211 = 8655590
487 + 8655103 = 8655590

Showing the first eight; more decompositions exist.
