Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493938, here are decompositions:

7 + 493931 = 493938
19 + 493919 = 493938
41 + 493897 = 493938
61 + 493877 = 493938
79 + 493859 = 493938
127 + 493811 = 493938
131 + 493807 = 493938
191 + 493747 = 493938

Showing the first eight; more decompositions exist.
