Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6784, here are decompositions:

3 + 6781 = 6784
5 + 6779 = 6784
23 + 6761 = 6784
47 + 6737 = 6784
83 + 6701 = 6784
131 + 6653 = 6784
233 + 6551 = 6784
263 + 6521 = 6784

Showing the first eight; more decompositions exist.
