Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493286, here are decompositions:

7 + 493279 = 493286
37 + 493249 = 493286
43 + 493243 = 493286
67 + 493219 = 493286
109 + 493177 = 493286
127 + 493159 = 493286
139 + 493147 = 493286
163 + 493123 = 493286

Showing the first eight; more decompositions exist.
