Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493840, here are decompositions:

23 + 493817 = 493840
29 + 493811 = 493840
47 + 493793 = 493840
107 + 493733 = 493840
131 + 493709 = 493840
197 + 493643 = 493840
233 + 493607 = 493840
257 + 493583 = 493840

Showing the first eight; more decompositions exist.
