Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491358, here are decompositions:

5 + 491353 = 491358
17 + 491341 = 491358
19 + 491339 = 491358
29 + 491329 = 491358
31 + 491327 = 491358
59 + 491299 = 491358
61 + 491297 = 491358
79 + 491279 = 491358

Showing the first eight; more decompositions exist.
