Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488866, here are decompositions:

5 + 488861 = 488866
107 + 488759 = 488866
137 + 488729 = 488866
149 + 488717 = 488866
179 + 488687 = 488866
227 + 488639 = 488866
233 + 488633 = 488866
239 + 488627 = 488866

Showing the first eight; more decompositions exist.
