Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493138, here are decompositions:

5 + 493133 = 493138
11 + 493127 = 493138
17 + 493121 = 493138
29 + 493109 = 493138
71 + 493067 = 493138
89 + 493049 = 493138
137 + 493001 = 493138
227 + 492911 = 493138

Showing the first eight; more decompositions exist.
