Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581736, here are decompositions:

5 + 581731 = 581736
7 + 581729 = 581736
37 + 581699 = 581736
53 + 581683 = 581736
73 + 581663 = 581736
79 + 581657 = 581736
97 + 581639 = 581736
137 + 581599 = 581736

Showing the first eight; more decompositions exist.
