Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493942, here are decompositions:

3 + 493939 = 493942
5 + 493937 = 493942
11 + 493931 = 493942
23 + 493919 = 493942
83 + 493859 = 493942
89 + 493853 = 493942
131 + 493811 = 493942
149 + 493793 = 493942

Showing the first eight; more decompositions exist.
