Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581746, here are decompositions:

3 + 581743 = 581746
17 + 581729 = 581746
47 + 581699 = 581746
59 + 581687 = 581746
83 + 581663 = 581746
89 + 581657 = 581746
107 + 581639 = 581746
149 + 581597 = 581746

Showing the first eight; more decompositions exist.
