Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4058, here are decompositions:

7 + 4051 = 4058
31 + 4027 = 4058
37 + 4021 = 4058
127 + 3931 = 4058
139 + 3919 = 4058
151 + 3907 = 4058
181 + 3877 = 4058
211 + 3847 = 4058

Showing the first eight; more decompositions exist.
