Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4018, here are decompositions:

5 + 4013 = 4018
11 + 4007 = 4018
17 + 4001 = 4018
29 + 3989 = 4018
71 + 3947 = 4018
89 + 3929 = 4018
101 + 3917 = 4018
107 + 3911 = 4018

Showing the first eight; more decompositions exist.
