Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19782, here are decompositions:

5 + 19777 = 19782
19 + 19763 = 19782
23 + 19759 = 19782
29 + 19753 = 19782
31 + 19751 = 19782
43 + 19739 = 19782
73 + 19709 = 19782
83 + 19699 = 19782

Showing the first eight; more decompositions exist.
