Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491356, here are decompositions:

3 + 491353 = 491356
17 + 491339 = 491356
23 + 491333 = 491356
29 + 491327 = 491356
59 + 491297 = 491356
83 + 491273 = 491356
137 + 491219 = 491356
197 + 491159 = 491356

Showing the first eight; more decompositions exist.
