Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488938, here are decompositions:

17 + 488921 = 488938
29 + 488909 = 488938
41 + 488897 = 488938
59 + 488879 = 488938
179 + 488759 = 488938
227 + 488711 = 488938
251 + 488687 = 488938
311 + 488627 = 488938

Showing the first eight; more decompositions exist.
