Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493940, here are decompositions:

3 + 493937 = 493940
43 + 493897 = 493940
67 + 493873 = 493940
127 + 493813 = 493940
163 + 493777 = 493940
193 + 493747 = 493940
211 + 493729 = 493940
229 + 493711 = 493940

Showing the first eight; more decompositions exist.
