Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4028, here are decompositions:

7 + 4021 = 4028
61 + 3967 = 4028
97 + 3931 = 4028
109 + 3919 = 4028
139 + 3889 = 4028
151 + 3877 = 4028
181 + 3847 = 4028
331 + 3697 = 4028

Showing the first eight; more decompositions exist.
