Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580990, here are decompositions:

71 + 580919 = 580990
89 + 580901 = 580990
101 + 580889 = 580990
131 + 580859 = 580990
197 + 580793 = 580990
227 + 580763 = 580990
233 + 580757 = 580990
257 + 580733 = 580990

Showing the first eight; more decompositions exist.
