Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581760, here are decompositions:

7 + 581753 = 581760
17 + 581743 = 581760
29 + 581731 = 581760
31 + 581729 = 581760
59 + 581701 = 581760
61 + 581699 = 581760
73 + 581687 = 581760
97 + 581663 = 581760

Showing the first eight; more decompositions exist.
