Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491198, here are decompositions:

31 + 491167 = 491198
61 + 491137 = 491198
139 + 491059 = 491198
157 + 491041 = 491198
229 + 490969 = 491198
241 + 490957 = 491198
271 + 490927 = 491198
277 + 490921 = 491198

Showing the first eight; more decompositions exist.
