Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488878, here are decompositions:

17 + 488861 = 488878
149 + 488729 = 488878
167 + 488711 = 488878
191 + 488687 = 488878
227 + 488651 = 488878
239 + 488639 = 488878
251 + 488627 = 488878
311 + 488567 = 488878

Showing the first eight; more decompositions exist.
