Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491204, here are decompositions:

3 + 491201 = 491204
37 + 491167 = 491204
67 + 491137 = 491204
163 + 491041 = 491204
211 + 490993 = 491204
277 + 490927 = 491204
283 + 490921 = 491204
313 + 490891 = 491204

Showing the first eight; more decompositions exist.
