Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581790, here are decompositions:

17 + 581773 = 581790
23 + 581767 = 581790
37 + 581753 = 581790
47 + 581743 = 581790
59 + 581731 = 581790
61 + 581729 = 581790
89 + 581701 = 581790
103 + 581687 = 581790

Showing the first eight; more decompositions exist.
