Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491146, here are decompositions:

17 + 491129 = 491146
107 + 491039 = 491146
179 + 490967 = 491146
197 + 490949 = 491146
233 + 490913 = 491146
269 + 490877 = 491146
317 + 490829 = 491146
449 + 490697 = 491146

Showing the first eight; more decompositions exist.
