Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491446, here are decompositions:

17 + 491429 = 491446
23 + 491423 = 491446
29 + 491417 = 491446
89 + 491357 = 491446
107 + 491339 = 491446
113 + 491333 = 491446
149 + 491297 = 491446
167 + 491279 = 491446

Showing the first eight; more decompositions exist.
