Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493858, here are decompositions:

5 + 493853 = 493858
41 + 493817 = 493858
47 + 493811 = 493858
137 + 493721 = 493858
149 + 493709 = 493858
251 + 493607 = 493858
317 + 493541 = 493858
401 + 493457 = 493858

Showing the first eight; more decompositions exist.
