Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488986, here are decompositions:

5 + 488981 = 488986
89 + 488897 = 488986
107 + 488879 = 488986
227 + 488759 = 488986
257 + 488729 = 488986
263 + 488723 = 488986
269 + 488717 = 488986
347 + 488639 = 488986

Showing the first eight; more decompositions exist.
