Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7844, here are decompositions:

3 + 7841 = 7844
103 + 7741 = 7844
127 + 7717 = 7844
157 + 7687 = 7844
163 + 7681 = 7844
223 + 7621 = 7844
241 + 7603 = 7844
271 + 7573 = 7844

Showing the first eight; more decompositions exist.
