Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3784, here are decompositions:

5 + 3779 = 3784
17 + 3767 = 3784
23 + 3761 = 3784
83 + 3701 = 3784
107 + 3677 = 3784
113 + 3671 = 3784
167 + 3617 = 3784
191 + 3593 = 3784

Showing the first eight; more decompositions exist.
