Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3850, here are decompositions:

3 + 3847 = 3850
17 + 3833 = 3850
29 + 3821 = 3850
47 + 3803 = 3850
53 + 3797 = 3850
71 + 3779 = 3850
83 + 3767 = 3850
89 + 3761 = 3850

Showing the first eight; more decompositions exist.
