Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491254, here are decompositions:

3 + 491251 = 491254
41 + 491213 = 491254
53 + 491201 = 491254
83 + 491171 = 491254
173 + 491081 = 491254
251 + 491003 = 491254
263 + 490991 = 491254
317 + 490937 = 491254

Showing the first eight; more decompositions exist.
