Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581994, here are decompositions:

11 + 581983 = 581994
13 + 581981 = 581994
41 + 581953 = 581994
47 + 581947 = 581994
53 + 581941 = 581994
73 + 581921 = 581994
103 + 581891 = 581994
131 + 581863 = 581994

Showing the first eight; more decompositions exist.
