Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3922, here are decompositions:

3 + 3919 = 3922
5 + 3917 = 3922
11 + 3911 = 3922
41 + 3881 = 3922
59 + 3863 = 3922
71 + 3851 = 3922
89 + 3833 = 3922
101 + 3821 = 3922

Showing the first eight; more decompositions exist.
