Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3826, here are decompositions:

3 + 3823 = 3826
5 + 3821 = 3826
23 + 3803 = 3826
29 + 3797 = 3826
47 + 3779 = 3826
59 + 3767 = 3826
107 + 3719 = 3826
149 + 3677 = 3826

Showing the first eight; more decompositions exist.
