Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491164, here are decompositions:

5 + 491159 = 491164
83 + 491081 = 491164
173 + 490991 = 491164
197 + 490967 = 491164
227 + 490937 = 491164
251 + 490913 = 491164
431 + 490733 = 491164
467 + 490697 = 491164

Showing the first eight; more decompositions exist.
