Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83784, here are decompositions:

7 + 83777 = 83784
11 + 83773 = 83784
23 + 83761 = 83784
47 + 83737 = 83784
67 + 83717 = 83784
83 + 83701 = 83784
131 + 83653 = 83784
163 + 83621 = 83784

Showing the first eight; more decompositions exist.
