Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39782, here are decompositions:

3 + 39779 = 39782
13 + 39769 = 39782
73 + 39709 = 39782
79 + 39703 = 39782
103 + 39679 = 39782
151 + 39631 = 39782
163 + 39619 = 39782
241 + 39541 = 39782

Showing the first eight; more decompositions exist.
