Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493216, here are decompositions:

5 + 493211 = 493216
23 + 493193 = 493216
47 + 493169 = 493216
83 + 493133 = 493216
89 + 493127 = 493216
107 + 493109 = 493216
149 + 493067 = 493216
167 + 493049 = 493216

Showing the first eight; more decompositions exist.
