Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491214, here are decompositions:

13 + 491201 = 491214
43 + 491171 = 491214
47 + 491167 = 491214
131 + 491083 = 491214
173 + 491041 = 491214
211 + 491003 = 491214
223 + 490991 = 491214
257 + 490957 = 491214

Showing the first eight; more decompositions exist.
