Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581958, here are decompositions:

5 + 581953 = 581958
11 + 581947 = 581958
17 + 581941 = 581958
37 + 581921 = 581958
67 + 581891 = 581958
89 + 581869 = 581958
101 + 581857 = 581958
137 + 581821 = 581958

Showing the first eight; more decompositions exist.
