Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7784, here are decompositions:

31 + 7753 = 7784
43 + 7741 = 7784
61 + 7723 = 7784
67 + 7717 = 7784
97 + 7687 = 7784
103 + 7681 = 7784
163 + 7621 = 7784
181 + 7603 = 7784

Showing the first eight; more decompositions exist.
