Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3862, here are decompositions:

11 + 3851 = 3862
29 + 3833 = 3862
41 + 3821 = 3862
59 + 3803 = 3862
83 + 3779 = 3862
101 + 3761 = 3862
191 + 3671 = 3862
239 + 3623 = 3862

Showing the first eight; more decompositions exist.
