Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493990, here are decompositions:

11 + 493979 = 493990
17 + 493973 = 493990
23 + 493967 = 493990
53 + 493937 = 493990
59 + 493931 = 493990
71 + 493919 = 493990
113 + 493877 = 493990
131 + 493859 = 493990

Showing the first eight; more decompositions exist.
