Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491776, here are decompositions:

3 + 491773 = 491776
29 + 491747 = 491776
107 + 491669 = 491776
137 + 491639 = 491776
149 + 491627 = 491776
239 + 491537 = 491776
293 + 491483 = 491776
347 + 491429 = 491776

Showing the first eight; more decompositions exist.
