Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493530, here are decompositions:

7 + 493523 = 493530
67 + 493463 = 493530
73 + 493457 = 493530
83 + 493447 = 493530
97 + 493433 = 493530
127 + 493403 = 493530
131 + 493399 = 493530
137 + 493393 = 493530

Showing the first eight; more decompositions exist.
