Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493978, here are decompositions:

5 + 493973 = 493978
11 + 493967 = 493978
41 + 493937 = 493978
47 + 493931 = 493978
59 + 493919 = 493978
101 + 493877 = 493978
167 + 493811 = 493978
257 + 493721 = 493978

Showing the first eight; more decompositions exist.
