Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3994, here are decompositions:

5 + 3989 = 3994
47 + 3947 = 3994
71 + 3923 = 3994
83 + 3911 = 3994
113 + 3881 = 3994
131 + 3863 = 3994
173 + 3821 = 3994
191 + 3803 = 3994

Showing the first eight; more decompositions exist.
