Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493818, here are decompositions:

5 + 493813 = 493818
7 + 493811 = 493818
11 + 493807 = 493818
41 + 493777 = 493818
71 + 493747 = 493818
89 + 493729 = 493818
97 + 493721 = 493818
107 + 493711 = 493818

Showing the first eight; more decompositions exist.
