Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491476, here are decompositions:

47 + 491429 = 491476
53 + 491423 = 491476
59 + 491417 = 491476
137 + 491339 = 491476
149 + 491327 = 491476
179 + 491297 = 491476
197 + 491279 = 491476
257 + 491219 = 491476

Showing the first eight; more decompositions exist.
