Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4002, here are decompositions:

13 + 3989 = 4002
59 + 3943 = 4002
71 + 3931 = 4002
73 + 3929 = 4002
79 + 3923 = 4002
83 + 3919 = 4002
113 + 3889 = 4002
139 + 3863 = 4002

Showing the first eight; more decompositions exist.
