Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580918, here are decompositions:

5 + 580913 = 580918
17 + 580901 = 580918
29 + 580889 = 580918
47 + 580871 = 580918
59 + 580859 = 580918
131 + 580787 = 580918
227 + 580691 = 580918
311 + 580607 = 580918

Showing the first eight; more decompositions exist.
