Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581748, here are decompositions:

5 + 581743 = 581748
17 + 581731 = 581748
19 + 581729 = 581748
47 + 581701 = 581748
61 + 581687 = 581748
109 + 581639 = 581748
131 + 581617 = 581748
149 + 581599 = 581748

Showing the first eight; more decompositions exist.
