Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3950, here are decompositions:

3 + 3947 = 3950
7 + 3943 = 3950
19 + 3931 = 3950
31 + 3919 = 3950
43 + 3907 = 3950
61 + 3889 = 3950
73 + 3877 = 3950
97 + 3853 = 3950

Showing the first eight; more decompositions exist.
