Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491488, here are decompositions:

5 + 491483 = 491488
59 + 491429 = 491488
71 + 491417 = 491488
131 + 491357 = 491488
149 + 491339 = 491488
191 + 491297 = 491488
227 + 491261 = 491488
269 + 491219 = 491488

Showing the first eight; more decompositions exist.
