Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580840, here are decompositions:

3 + 580837 = 580840
47 + 580793 = 580840
53 + 580787 = 580840
83 + 580757 = 580840
107 + 580733 = 580840
149 + 580691 = 580840
167 + 580673 = 580840
233 + 580607 = 580840

Showing the first eight; more decompositions exist.
