Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3974, here are decompositions:

7 + 3967 = 3974
31 + 3943 = 3974
43 + 3931 = 3974
67 + 3907 = 3974
97 + 3877 = 3974
127 + 3847 = 3974
151 + 3823 = 3974
181 + 3793 = 3974

Showing the first eight; more decompositions exist.
