Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491608, here are decompositions:

17 + 491591 = 491608
71 + 491537 = 491608
107 + 491501 = 491608
179 + 491429 = 491608
191 + 491417 = 491608
251 + 491357 = 491608
269 + 491339 = 491608
281 + 491327 = 491608

Showing the first eight; more decompositions exist.
