Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4012, here are decompositions:

5 + 4007 = 4012
11 + 4001 = 4012
23 + 3989 = 4012
83 + 3929 = 4012
89 + 3923 = 4012
101 + 3911 = 4012
131 + 3881 = 4012
149 + 3863 = 4012

Showing the first eight; more decompositions exist.
