Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491234, here are decompositions:

67 + 491167 = 491234
97 + 491137 = 491234
151 + 491083 = 491234
193 + 491041 = 491234
241 + 490993 = 491234
277 + 490957 = 491234
283 + 490951 = 491234
307 + 490927 = 491234

Showing the first eight; more decompositions exist.
