Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581984, here are decompositions:

3 + 581981 = 581984
31 + 581953 = 581984
37 + 581947 = 581984
43 + 581941 = 581984
127 + 581857 = 581984
163 + 581821 = 581984
211 + 581773 = 581984
241 + 581743 = 581984

Showing the first eight; more decompositions exist.
