Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581022, here are decompositions:

41 + 580981 = 581022
53 + 580969 = 581022
83 + 580939 = 581022
103 + 580919 = 581022
109 + 580913 = 581022
131 + 580891 = 581022
151 + 580871 = 581022
163 + 580859 = 581022

Showing the first eight; more decompositions exist.
