Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3954, here are decompositions:

7 + 3947 = 3954
11 + 3943 = 3954
23 + 3931 = 3954
31 + 3923 = 3954
37 + 3917 = 3954
43 + 3911 = 3954
47 + 3907 = 3954
73 + 3881 = 3954

Showing the first eight; more decompositions exist.
