Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493838, here are decompositions:

31 + 493807 = 493838
61 + 493777 = 493838
109 + 493729 = 493838
127 + 493711 = 493838
181 + 493657 = 493838
211 + 493627 = 493838
271 + 493567 = 493838
307 + 493531 = 493838

Showing the first eight; more decompositions exist.
