Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491216, here are decompositions:

3 + 491213 = 491216
67 + 491149 = 491216
79 + 491137 = 491216
157 + 491059 = 491216
223 + 490993 = 491216
367 + 490849 = 491216
379 + 490837 = 491216
433 + 490783 = 491216

Showing the first eight; more decompositions exist.
