Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493220, here are decompositions:

3 + 493217 = 493220
19 + 493201 = 493220
43 + 493177 = 493220
61 + 493159 = 493220
73 + 493147 = 493220
97 + 493123 = 493220
109 + 493111 = 493220
127 + 493093 = 493220

Showing the first eight; more decompositions exist.
